R80.10 MAC Magic autodetection - when does it take place?

sk25977 says that "Starting in Gaia R80.10, the 5th byte of the Source MAC address (MAC magic) in all types of CCP packets (CCP Delta Sync packets, CCP Health Check packets, forwarded packets) is assigned automatically.  During the initial configuration of the cluster members, they apply the following algorithm to set the MAC magic value..."

What is meant by "the initial configuration of the cluster members"?  Does that happen just once at the creation of the cluster?  Or is it checked every time the cluster is started?  Or continuously during cluster operation?

What happens if we configure a cluster off the network first, then attached it to a vlan where another cluster already has the value 1?  How often is a duplicate value detected?
