If HR says "You can't have all high performers on a team", they are telling a manager that you aren't allowed to excel in your own job as a coach. They are literally telling you not to spend your time helping employees because some HR chart wizard is going to make you rank them anyways and you will have wasted your time.

This isn't saying to ignore others but recognize that people are at different stages of careers and will have different needs.
