I read the rules to be as Nightbreeze said. When you inflict a multiple of damage (usually just double) you roll the dice multiple times. You never roll once and multiply. That means that a roll of twice maximum damage for one crit is EXTREMELY improbable. (Happens one time out of sixty-four crits for a longsword, or other d8 weapon. And since a crit probably only happens about one time out of 100 attacks, we're talking about a 1 in 6400 probability, if I recall my math properly, which is by no means EVER certain!)
