It was noted on Wrestling Observer Live that the double count out was announced because the referee has to call the match like a shoot. Benjamin and Kingston apparently botched their spot and both teams were counted out.
The situation was even more confusing as heel MVP cut a somewhat-babyface promo on wanting the match to be re-started, while the babyface champions bragged about retaining via count out.
The match was re-started and Woods ended up rolling Benjamin up for the pin to retain.
