AlphaGo enlarged a group that was at risk of atari (loss to opponent) instead of correctly trying to divert attention to elsewhere on the board or starting a new fight or simply writing it off. If basically added stones to a group that was almost certainly dead and allowed the opponent to punish it heavily, thus giving away more stones than it had to.
