What I have always heard about this is much like what AJ said. The more relaxed, upright position with the hands resting on the tops keeps the upper body muscles relaxed and opens the chest for better breathing. I especially like this position when I am on a long climb where I can find a gear that allows me to spin along comfortably at 70-80 rpm.
