He means that the raised platform is not at the height of the deck level but actually above it, meaning that the width of the (outward slanting) superstructure of the 055 (and hence the deck width) will be wider than what is shown with the mock up because the mockup model is not showing the complete superstructure because the part below the platform but above the real deck is truncated in the mockup.

Okay, I'll reference these diagrams.
First of all, we need to understand that the platform on which the mock up sits is not the actual hull deck height. E.g.: The aft of the mock up platform is not the height of the helicopter hangar. Instead, the mock up platform is higher than the actual hull deck height, and the only part of the platform deck which is representative of the real thing is the height of the main gun. The diagram below demonstrates. Note how the actual height of the true hull deck is lower, shown by the notional helicopter flight deck/hull deck height being lower than the platform.
That has been the design for most recent PLAN DDGs and FFGs (see 054A below), so it is likely it will be the design for 055 as well. Also, if the platform deck height really were the hull deck height, then it would make no sense because the hangar is too low to even hold a Z-9 let alone a Z-18.
So, what does this mean for 055's actual beam?
I will use a handy 052D diagram to demonstrate -- we're talking about 055 but the principle is the same. The greatest width of a ship (i.e.: its beam) is usually found at the level of its true hull deck (the black line). On the other hand, in the 055 mock up's case, the platform "cuts" the ship "horizontally" a few decks higher than the true hull deck line, at about the red line.
Now, notice how the geometry of the ship above the true hull deck is like a triangle (green lines). So the further higher up you go relative to the true hull deck, the narrower your measured width becomes.
So, to quote you, you ask if the width of the mock up platform represents the bottom of the hull, correctly saying the bottom of the hull is narrower than the actual hull deck.
The answer is that I'm saying the width of the mock up platform represents a horizontal cross section a few decks above the actual hull deck -- and of course it is actually narrower than the actual hull deck as well.

What is your mother tongue? I might just know a native speaker to translate it for you.
By the way, if you don't mind me asking: what is your age and educational background?
Send me a private message with the answers if you prefer.
Thanks.

Oh no, not at all. The concept is so simple that I doubt anyone above the age of five would have trouble grasping it.
I was asking because some of the concepts are taught differently under different education systems, especially over in Europe, where a diverse range of pedagogical methodologies are in place, not to mention in other parts of the world.
I was hoping to find out his age and native language so that I might find someone who can offer an explanation in his mother tongue and appropriate to his age and education level. For all I know, he could be an eleven-year-old living in the Philippines, Bihar, Albania, or Quebec. I can even find someone who speak the dialect of the Bedouins.
Kroko is free to contact me via private message, and I'd be very happy to offer help.

Now i see. With these diagrams, i finally understand this whole mess. You have to understand that english is not my mothertongue. Sometimes you talk about technical terms that i dont understand much, but in this case i was just clueless.
hehe. I really wish i was eleven year old again. I think that you would be surprised if i told you my age and educacion. But there is no need to it.

Surprise me then, via private message.
Please refrain from repeatedly asking for others' personal details. It's just not proper etiquette, even on the internet.
Additionally, I would like to kindly remind everyone that while it is ultimately your decision on how much you reveal about yourself on an internet forum, please keep in mind that somethings are better kept hidden, for the sake of your own privacy. (This message does not target anyone in particular)
Nice depiction, however I think a few details are wrong such as size of its 's hangar structure, exaggerates the length of the smoke stack, underestimates the length of its bow, not to mention overall length as well.
Good drawing, but imo the real thing will be at least a little bit different.
Just realized the page seems to have been taken on an angle, making the parts at the bottom seem bigger than the top. Regardless, some proportion issues remain present on their 055
