Explanation:

ROLLBACK is a command that can bring the state of the data a step back, but not more than that. It will refer to the state corresponding to the last time you executed COMMIT. This means if you have already used COMMIT 10 times, ROLLBACK will have an effect on the last execution you have performed.
