Makes perfect sense to me as far as stopping power goes although I'm having a hard time explaining it. Its reversed for a purpose ....(stopping) or braking. Not just for the hell of it. I'm sure someone can put it into words for ya.
If you cup your hand to push you forward in the water (grip) , doesn't it make sense that if you wanted to stop quicker you'd point the cupped hand to the forward to catch the water (grip) to stop you quicker?
I know it sounds stupid but its the same idea.
