There's your problem....you aren't focusing on his shoulder.
He is doing exactly what you are telling him to do, even though you didn't realize it. Of course he is going to move his butt when you hit him in the butt! He's been taught to move away from pressure, that's what he is doing. Pressure is applied to one area of his body so he moves that area. Just re-focus your pressure to a different area of his body (his shoulder) and see if that part of his body moves away.
