There was apparently supposed to be an impressive AA figure on the opposite side of the room from the doors (on the left). It would naturally spread the crowd out a lot better. Sure there would still be a group of people that will squeeze up against the doors to the ride. However, a lot of people would drift to the left to see the AA. When the preshow ends, the group is already more spread out and it wouldn't be as much of a crunch.
Kind of like the HM stretching room. People that know, stand under the parasail girl for an easy exit, however, most people don't know where the exit is, and thus spread out.
