NS records are only supposed to point to addresses records (A/AAAA).
Pointing to CNAMES is not supported by the DNS protocol. Named
knows this so it never follows a CNAME when looking up addresses
of nameservers. This causes broken configurations to be detected
earlier and hopefully be fixed.

You are confused. BIND 8 and BIND 9 only look for A/AAAA and
in some versions A6 records.
