It's more than who is a better returner to be honest - one could argue that it is important to return the the odd points in a game well so that the team need not get into a break point situation.
For two right-handed players, the one with a stronger backhand will normally take the ad court so that they can confidently return wide balls on that side. I think that works well with the Bhupathi-Paes pairing since most would regard Bhupathi to have the better backhand and Paes to have the better forehand (especially when stepping in to attack the net).
