You hit the nail on the head. Just keep in mind that the dude's a troll digging a hole, man. In no universe does "we" signify everyone (at least in no universe with people who actually understand and comprehend the English language)--it signifies more than one individual.
Now, in my signature, I say "we all," which does indeed indicate that, but that's mainly for dramatic effect as that's been my signature for well over two years.
