Data replication for local volume

During the lesson of DEV-301 course, it is mentioned a ”local" MapR volume is created to store the intermediate map results.Now, this volume is called "local" because its contents are not replicated across the MapR cluster.Now in the second paragraph, it is also mentioned if there is contention, the MapR-FS will delete replicated containers on the data node in favor of the local volume. These deleted replicas are then replicated to other data nodes in order to maintain the desired redundancy.

So I find these two explanations contradictory.Can you help me to understand this? I am also attaching a slide guide screenshot for your reference.
