All the servers are right.  the "h" and "anytld" servers evidently "chase" to the end see the authority section, and the others "chase" only within the first zone.  It seems to be a matter of how aggressive the particular nameserver code is (or is configured to be).

(See: $ for ns in `dig xn--kprw13d. ns +short`; do echo $ns ;dig @$ns example.xn--kprw13d. ns +dnssec; done)
