Otherwise it might have been the most overbooked ending in quite sometime. It really was not well managed and made the whole title picture very unclear. It looked like Seth and Ambrose pinning each other at the same time was to set up a "who is the true champion" story. Then when Ambrose and Rollins end up on different shows tonight, they can just have them both hold major titles.
The one issue is battleground. The only way I can see it making sense is if the triple threat at battleground turns into a 2 out of 3 falls match, where both disputed titles are on the line. The first fall is for one title and the second fall is for the other. If Rollins or Reigns win a title, they take it to Raw and if Ambrose wins a title he take it to SD. I would doubt anyone would win both and then make them into one title again.
