My mistake, I was actually using bind 8's dig.

F root is reporting version 9.2.2rc1, which puts the response to an NS
query for a zone it's not authoritative for in the authority section. You
can see the difference if you query it for . (the root zone) without the
+short option. This is actually the correct behavior, since the root
servers aren't authoritative for the TLD zones. BIND 8 got this wrong,
BIND 9 fixes that mistake.

Sorry for the confusion,
