"He's a sleeper agent." "Sometimes memory is correct, memory is incorrect." "There's a certain sort of primal instinct that comes out that is not the Tyler that we know." I think it's Talking Heads. They don't want to speak in absolutes so they can keep discussion going on After Trek. One-sentence answers are the last thing people want to go with in a free-flowing open forum. I think it's less about whether or not Ash is Voq (as far as I'm concerned it's spelled out now that he is) and more about two personas in conflict with each other. Where does one begin and other end? How do you cope with being one thing when you thought you were something else entirely? Memory can be incorrect because you're misinterpreting something that happened or it's incorrect because they never did. It can be both.
