Which isn't correct in that it is one way in which you can have multiple master sockets. I have wired many systems with multiple masters in other ways. As I said earlier, it is not necessarily recommended to have multiple masters but having multiple masters is unlikely to make anything stop working.
What you say above is correct regarding the ring wire and RF, but that would usually be wired with multiple secondary sockets, not masters, so is not relevant to this.
