In some actions, yes, he wants to appear as successful multi millionaires. In some other actions, he sounds like a billionaire. That's why he is seen as a weird multi-millionaire. He is not cheap either, but doesn't trust anyone: he feeds you information, to see whether you share that with other people; he says, he trusts you, later he can send a private detective to see what you are up to.
I think, the root cause is this: just as FAANG engineers's social circle is fellow people working from FAANG, it is the same for wealthy, super, uber wealthy. You don't see a FAANG guy living in a mobile home surrounded by people who work in the blue collar folks.
Some folks don't want to involve in many social activities of the class they belong to, but want to be part of the lower classes. That's what I mean by 'pass themselves off as'.
