It's interesting that.
Looking at it, I'd assume the emergency door being on the opposite side to the entrance/exit was incase of a collision to the side of the vehicle, if it was balanced on a cliff edge or if it toppled over on to its side for example.
Basically ensuring that there was always an escape route.
That's not going to always be the case on a dual-door vehicle and may need the use of the tungsten hammer to escape.
