AbuseFilter's revert feature

Hello. I don't see what revert feature means. It might be (a) reverting all actions (edit, move etc.) logged by AbuseFilter or (b) reverting all measurement (so applying disallowed edits or restoring removed autoconfirmed status etc.) Which one is correct? It will be greatly helpful for translation. Thank you.

Abuse filters can (apparently) have impact on content. The 'revert' feature of the extension allows someone with sufficient access rights to revert whatever abusefilter did that can be reverted.
