It is definitely an ugly motion, but I think it was actually designed to tone down his forehand, and maybe it helps him in that way. Gulbis forehand was a very powerful shot, but it was so powerful that he went for winners all the time and hit a lot of UEs. This new movement has such a long takeback that, unless it is a ball that sits up, he will normally not go for a winner.
I just think that this might help his game more tactically than technically in that it limits his choices. Gulbis could play so many shots that it drove himself crazy
