Like someone can only be a head writer for three straight series. They can be the head writer again after someone else has had at least one season as head writer. So writer Y can be head writer for series 1,2,3 but then they cannot do a fourth straight series so writer Z gets a chance and does series 4. Then after someone else has had a turn then write Y can be head writer for series 5,6,7 and so on.
