For each release there are two release managers. After each release the release manager having managed two releases steps down and the release management team of the last release appoints a new release manager.

This makes sure a release management team always consists of one release manager who already has managed one release and one release manager being introduced to their role, making it easier to pass on knowledge and experience.
