"Kinda." He won't instill a sense of false hope where it isn't owed, or where it shouldn't exist. Even if she forgets it later, it's just a plain shitty thing to do, and he'd like to think that he's not so terrible that he'd inflict that kind of thing on her out of pity. "I dunno. It's a little like seeing a ghost, sometimes."

The only reason he can say this at all is because he knows, understands, to some extent - that she gets it. Because she would. The strangeness of seeing things being done and said by someone who was you but wasn't.
