It's not a battle royal though, is it? The rules as explained on WWE.com indicate that they're gonna all be inside the ring (and/or surrounding it in separate brawls with one another) at the same time and then one fall, pin fall or submission, will end the entire match. I doubt they'd have two battle royals on the same show.
I thought the rules at first were going to be the same gauntlet-style rules that the Cruiserweight Open match from Wrestlemania 20 had where two people start in the ring and once one of them gets eliminated, another comes in until only one man is left standing, but it seems that isn't the case. Now that it's only one fall to the finish, I'm betting that AJ manages to just barely squeak by with the victory and then Tamina becomes thirsty for the gold, turns on her in the subsequent weeks, and then takes the championship from her at Extreme Rules.
