Such a server does this by knowing, and honestly serving up to you, a fresh and complete set of tagged-elephants. “Rollback” is serving you a version of the set that existed at some previous time, so the honest server giving you a copy of the most recent set protects you from rollback attack. “Selection” is omitting some elephants from the set, so the honest server giving you a complete copy of the set protects you from selection attack.
