Clarify limits of replication topologies

The Admin Guide section describing replication topologies
introduces the idea of “sub-topologies” without explaining it.
This patch clarifies what is meant,
and breaks up a long sentence to make the text easier to digest.

Thanks to Fabio for pointing out the problem and reviewing over IM.
