Oh ok, I'm sorry. I was imagining you meant the other way.
It wouldn't hurt to put some blocking at the seam. If it's a garage that is getting the standard treatment, I wouldn't put blocking. If it's going to be a finished space, I'd put in blocking. Takes all of 3 minutes to cut the wood and throw a couple of screws in.
