How do you make sure of that? With atomic consistency guarantees you can "just" roll back the transaction -- nobody else would have seen any values contained in it. In an eventually consistent system some parts will have started building on the new values so you can't roll them back. You have to give up on consistency and achieve it only in a "best effort" sense.
