If it's a true 100% partition between the two chains, ie all transaction sources are disjoint (or potentially have enough coin to cover all transactions that exist on both chains) couldn't anyone that's taken actions based on transactions on the losing chain resubmit transactions to the winning chain and they'd eventually get picked up? (I've not dug into the protocol at a super deep level so I'm not 100% on what protections are in place that might stop this from working given a properly signed transaction.)
