Short answer: it is correct, working as designed.
Long answer:
That answer came from a DNS cache, which by definition is not authoritative -
it is merely a copy (which you trust to be legit)
It does match the actual records on the real auth servers:
===========
$ dig NS gentoo.org +trace
[snip]
gentoo.org. 86400 IN NS ns1.gentoo.org.
gentoo.org. 86400 IN NS ns2.gentoo.org.
;; Received 96 bytes from 199.19.56.1#53(a0.org.afilias-nst.info) in 460 ms
gentoo.org. 86400 IN NS ns1.gentoo.org.
gentoo.org. 86400 IN NS ns2.gentoo.org.
