If he had Wisconsin as a 1 seed, it would make sense, but he still has them as a 2. He must be having the same thought that I've had, which is that the possibility of Wisconsin ending up in UK's region (when they either should be a 1, or have a very good argument to be a 1) has gotten so much bad publicity that the selection committee will avoid doing it.
There's also the chance that he rearranges things just for the sake of doing so. More hits on his page is not a bad thing for him.
