I don't see why you wouldn't be able to do the event twice, if you have your account synced. I'm pretty sure they made a PC and Pocket version because they've already done a Village of Treasures for PC, but they've not yet finished coding it for Pocket. That's my guess on why there are two events. :)

At least, I'm hoping that's the case so that we have another chance to obtain Kogarasumaru. The only way we'll know for sure is when the event releases, or the staff confirm you'll be able to run the event again on a synced Pocket account.
