I believe I begin to see the source of your confusion.  Look
back in the abstract:

  These practices presume that a single entity remains 
  administratively and operationally responsible for each 
  of the distributed servers.

This should probably be updated to say something like "distributed
server groups", because I mean that the whole paper presumes a single
organization handles all of the servers associated with a single
shared unicast address.  So ISP FOO might handle z.root-servers.net,
with distributed copies at various places in its network topologies.
I initially used the language "each of the distributed servers",
because I presumed that the practice might be common for operators
of root servers.
