I post at the canter a lot. The reason I do it is to get my leg in the right position & when you are riding a hot horse it is an easier method than to be constantly on their backs or constantly in a two point. I hover gently in the air, technically not a full two point or in a seat. I almost always do it when I am jumping. It helps keep timing, to keep your heels waaaay down & keep your position correct. I don't post huge though, not like the videos you have been showing. It's a slight, close contact post. Boy, are these things hard to explain! ha! I personally like doing them much more than flat out two points when you have no contact with the horse. It's almost like you are allowing the horse to gently push you into a slight post. Once again, I am not the best at explaining so I am not that much help.
