Is it a red flag when a guy asks you if you think he's an introvert or extrovert?

I don't find anything wrong with the question alone. My sister's husband asked this of me because I think most people don't know he's an introvert. He's actually not shy at all. So I thought he was an extrovert but actually he's an introvert. He unwinds at home.

No, it isn’t.
