When you have Display Names activated, firstly Mad Mimi unsubscribes the contact from all lists–it’s the polite thing to do! Then, its up to your contact to jump back in to an active list.
And if a contact only belongs to one list, that contact will just see a normal unsubscribe page. We gotcha covered there.

When I click the box next to the list name, I’ll be added back to that list.
