it seem to me zoneedit does not provide valid A records of their nameservers for ORG zone, which makes a simple request for glue records look confusing (all ORG authorized servers produce the same output):
am i wrong, or ADDITIONAL SECTION should also include A records of both ns9.zoneedit.com and ns17.zoneedit.com for ORG as it does for COM:root@foo:/var/log/bind9# dig +norec @b0.org.afilias-nst.org. artemyev.org NS
; <<>> DiG 9.7.3 <<>> +norec @b0.org.afilias-nst.org. artemyev.org NS
