and delete replication should match to avoid inconsistent picture between the clusters. It is not recommended to turn on asymmetric replication - for e.g. if three sites A,B,C are participating in replication, it would be better to avoid replication setups like A -> [B, C], B -> A. In this particular example, an object uploaded to A will be replicated to B,C. If replica metadata sync is turned on in site B, any metadata updates on a replica version made in B would reflect in A, but not in C.
