This exact thing happened in a game during Stallings tenure as coach. I don't think it was planned, I think the captains in the game got confused during the coin toss/decision time, but Alabama ended up kicking off to whoever the opponent was in the first half and then kicked off again to them at the start of the 2nd half. Stallings was asked about it after the game and he said it was a mix up, so it wasn't done for field position. And we won the game so no big deal was made of it.
Using hindsight, it does seem like it would have been a good idea in this year's AU game though.
