Either back him up for a long ways, or do some sending exercises, or lunge him on the spot...like as SOON as he moves that hind end you move his feet hard and fast. IF he is indeed a well broke horse, he will catch on really quickly to the fact that, "dang, this woman means business, maybe I had best stand still at the mounting block!!!"
I don't put up with nonsense like that, especially out of a horse that I KNOW should know better! Like my mare the other day, started backing up when I went to put on her bell boots...I put her into a back up, and then started sending her back and forth, til she was puffing a bit, brought her back up to where we had originally started, dropped her lead back on the ground, and she stood like she knew she was supposed to in the first place.
