I think what PAF utilized is a less sophisticated version of what PLAAF operates right now. I would think that once they have J-36, it involves to something newer. The level of control that J-36 would exert over surrounding aircraft (especially large drones) would be at a much higher level than currently you see between AWACS and fighter jet. If you make your command and control aircraft several magnitude more survivable, then that should pretty radically change how you fight.
None of that contradicts what Siege wrote -- the relevant part which I quote: "What got CAC engineers shitfaced drunk with happiness is not so much that their product is combat proven, but that there real life evidence that their interpretation of next generation aerial warfare is correct. J-36’s radical design and combat philosophy is actually the correct path forward."
The best way to view it is that the IAF-PAF skirmish (and the demonstration of PAF capabilities), current PLAAF capabilities, and future PLAAF capabilities inclusive of J-36's conops, all lie on the same concept of how aerial combat will go, but they exist at very different parts of the spectrum in terms of scale, complexity and sophistication.
