No. The reason for multiple nameservers is to remove single points of failures. Using three consecutive addresses doesn't remove single points of failure in the routing system.
If their goal is distribute a service for the benefit of their own = customers, then keeping all anycast nodes associated with that service = on-net seems entirely sensible.
Which only helps if *all* customers of those servers are also on net.
