I think you're reading that comment overly literally. But even if you're right, the psychological state you're deriving from it does not necessarily follow. You're the one filling in that step, and then using it to attack someone else ("bad faith"). That's the part we ask people not to do here, for what should be obvious reasons. Before you get to "the poster is either self-deceived", your post here is a fine critical comment and could easily just stop there.
