With the 2 satellite configuration, you can switch primaries and there's no need to silo data because it's still talking to all datacenters. However if there's a loss of a DC, or an outage that lasted long enough, then you could disable the secondary satellite (https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=399278313#CEP58:SatelliteDatacenters-Secondary/SatelliteDisableProcess) and data would then start being siloed for recovery when the dc comes back.

The replication is configured at the keyspace level, so two tables can't, but 2 keyspaces could. Since it's just a replication setting, there wouldn't be anything stopping you from doing things like having a DC that is a satellite for one keyspace, a primary for another, and a secondary for another. I'm not sure why you'd do that, but it is possible.
