Probably a possible “checkpoint” from Denuvo or similar DRM manufacturers. One would define an “event” for the DRM to trigger. Sometimes it’s starting the game, starting a New Game, loading game/saving game, and so on. Perhaps Capcom thought to (perhaps aptly?) make the check that if you kill a zombie in the zombie game, it checks if you bought the rights to do so.
