New roots normally form near the growing point which is located in the upper part of the rhizome. These actively growing roots help to keep the rhizome from rotting.
Areas of the rhizome that do not have healthy roots tend to rot, so by removing the part of the rhizome that would normally not produce new roots I'm proactively mitigating potential issues with rotting.
If I planted the entire rhizome there's a good chance the lower part of the rhizome would start to rot and depending on the variety that rot could spread to the growing point and kill the plant.
The added bonus is that the lower rhizome that I left potted will begin to rot and die which in turn activates it's survival mechanism to quickly produce new buds. These new buds will need to be removed before the rots reaches them.
