Narrative:
Air carrier Y; B752; clearing runway 25L after landing; air carrier X; B738; over threshold runway 25L. Supervisor instructed local controller to issue go around to air carrier X even though air carrier Y was clearing runway. Air carrier X then executed right turn off departure end runway 25L; turning in front of a departure; without instruction. Local controller turned air carrier X in time to prevent another incident. Second incident would have been prevented if not for go around.
