I can only guess that they put limits on promotion rates in order to make the senior management more equitable over time as the current leadership retires, rather than force termoil through rapid replacement of leadership across many many roles at the same time. The intention was to put a cap on the percentage of men that get newly promoted into those roles, but the law was written in a gender-neutral way.
