I think you are right. That Type-071 unit has not been parked behind the lead 075 for a while.
But it's so strange...
Here's an image taken about six days ago (or so I believe). Notice all the close-in weapons are missing (marked by red arrows):
Here's an image taken shortly after the launch (from last September). Mysteriously, all the close-in weapons (or stand-ins) were in place and wrapped in dark green tarp, as indicated by the red arrows.
This was the source of my original (mistaken) claim: what I thought was the re-appearance of close-in weapons wrapped in orange tarp.
