The way *I* see backstabbing is not simply striking them in the back. That would be the attacks you get as somebody leaves a room.
A backstab is a precise attack designed to inflict maximum damage. You can't really do TWO precise shots at the same time, at least it would be a completely different maneuver.
I actually picture backstab as a two hands on one dagger for maximum penetration. But if you can do it with another dagger in your hand or a shield in the other it makes the mechanics a lot easier.
