Except that decision doen't make a lot of sense.

If there is some advantage to delegating NS's for individual
addresses instead of using CNAME's I think you forgot to 
mention it.  CNAME's inherit the robustness of the referenced
domain.  If you do it by delegation, you'll have to provide
multiple NS records for every address, and the admin of the
delegating zone must track any changes.  The point of using
CNAMEs is for the delegating zone to not need to track anything
about the real names - if they did they could just supply the
correct PTR address in the first place.
