When I used to show on the hunter-jumper circiut I witnessed some pretty nasty accidents resulting from that form of dismount..the worst of them with someone catching their heel in the reins & comming off directly on her neck breaking it.There is not much of a way to "abort left off" from this position if say the horse spooks or you just get off balance. Horses generally do not like getting clunked in the side of the head or neck.
