The vandal did multiple edits. Instead of vandalizing in one go, they performed many small vandalizm many times. This is suck, especially for huge pages. Thankfully, that's just a normal quest page.

Undo is just for one single revision. For this case of vandalizm, that's when you use Rollback. With rollback, you can instantly reverts a page to a state before that person vandalized it, basically undoing all the vandal's edits.
