If he wasn't getting the right response, he'd say something about how ChatGPT wasn't getting it and that he'd try to re-explain it later.
The bullet points from the LessWrong article don't entirely map to the content he was getting, but I could see how they would resonate with a LessWronger using ChatGPT as a conversation partner until it gave the expected responses: The flattery about being the first to discover a solution, encouragement to post on LessWrong, and the reflection of some specific thought problem are all themes I'd expect a LessWronger in a bad mental state to be engaging with ChatGPT about.

I'm not convinced ChatGPT is hatching these ideas, but rather reflecting them back to the user. LessWrong posters like to post and talk about things. It wouldn't be surprising to find their ChatGPT conversations veering toward confirming that they should post about it.
In other cases I've seen the opposite claim made: That ChatGPT encouraged people to hide their secret discoveries and not reveal them. In those cases ChatGPT is also criticized as if it came up with that idea by itself, but I think it's more likely that it's simply mirroring what the user puts in.
