Many games are narrative dependent. When games have voice overs that get cut off due to a new scene being loaded or an interaction with another AI it can cause disruption in the story line leaving holes or questions unanswered. Continuing a voice over during level changes continues the story but effectively keeps the player engaged where there is usually a dead spot.
