Asynchronous simultaneous turn-based play in Game Center?

[Adams Immersive]

Does Game Center’s asynchronous turn-based multiplayer support allow both players to submit turns simultaneously instead of alternately? In other words, Game Center would advance the game and send the notification only after both players have transmitted their turn. Then, EITHER player would be allowed to submit the next turn immediately—neither has to wait for the other.

Kil-A-Ton is an example of simultaneous turn-based play (but it’s not Game Center).

Thanks in advance! I have some simultaneous game ideas that wouldn’t be practical (for a team of me!) without Game Center on the back end.
