Halo 4 Theater Help

Could someone explain to me how this works?

In Halo: Reach a listing of previously played multiplayer games would be collected in the theater. After playing, a user could then go into the theater and watch any of the games that he or she recently played.

In Halo 4, it appears as though only the most recently played game ends up getting saved. Am I doing something wrong or does the game really only save one match? It would be very unfortunate if 343 expects gamers to break up their parties just to capture a video.
