He has very good reason to suspect that Harry knows something about the prophecy. He doesn’t know that Harry knows the actual wording. He may not know the actual wording himself, though I’d have thought HPMOR!Quirrell would have found a way to find it out.
He already heard it from Snape, and can reasonably expect that after Voldemort’s supposed return Dumbledore&co. would share it with Harry. It doesn’t sound like Snape was thrown out partway through the prophecy the way he was in canon.

Good point.
