What they describe is a typical slave server. I wonder if they are misusing the term master for authoritative. They are correct that more than one server "is needed in order to maintain the availability of the domain should the Primary become unavailable." It's a good idea to make sure that your DNS servers are physically separated so a network failure does not block access to all of them. I would just let zone transfers take care of keeping things in sync instead of using rsync and a bunch of custom procedures to so it.
