Actually, he's continuing to refuse to answer.  He keeps trying to play these word games to make it look like he's denying that's his alt without really denying it.  He seems to be trying to preserve some kind of way to deny that he has lied about this while making it look to the quick skim reader that his is denying it.   However, his phrasing here is so painfully awkward that it ends up drawing more suspicion than if he just spoke plainly about it.  In that quote, he purposely says that I am wrong, without making it clear what I am wrong about.  We already know that QS thinks I am wrong generally.  My favorite one of these so far was the signed message from his saying "this was the only newbie account he has used to post in this thread".  It's hilariously weird because no one was accusing him of using another newbie account.
