In theory, that could be true. It could even be that China is doing due diligence and trying to avoid tarnishing a reputation of an individual before enough evidence is collected: he's probably lost the support even if everything that happened was deemed "consensual" (not sure if you've read the original message from Peng, but there was a description of an encounter where his wife was in a room next door: I can't imagine that being considered commendable in any way).

But they would probably mention that because this has become such a hot topic: "investigations into Peng's accusations are ongoing" should not be such a hard thing to mutter out.

But even if they did do something proper yet invisible, the obvious pressure on Peng to withdraw her claims and act as if nothing happened are alarming. As is the attempt to rewrite history of the case. They did not even make her say something like "I was under duress/drunk/whatever" or "somebody else stole my phone and wrote that": there is obviously some respect for her public stature, but the main concern is with "health of the nation". By making it all a lie.
