Yes. Exactly this is the point.

Yes and no. The point is that the HA-communication is done via RSCT and the versions of the RSCT packages have to be consistent throughout the cluster at any time. This is why you have to split up the cluster into single nodes at one point (precisely the point where you update the RSCT). During this phase communication would not be possible. But as each node is single at this time it doesn't recognize this inability to communicate.

I hope this helps.
