	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.
