Without digging any further, this is one of the scariest parts. Maybe they say AES because their marketing is aimed at ignorant people, for which a bare "AES" still sounds good. But if they are thinking AES, then I'm afraid how insecure their chosen mode of operation (and implementation thereof) might be. Not too afraid though. The whole premise is bogus, there are less wasteful ways to manage passwords.
