Because it's contrary to itself.
You've specified norecurse, which means that if nameserver believes it has
authorative data it should return it, if it doesn't it should return a
referral (and no answer beside it).
But the server returns answer (which means it believes it has authorative
data), but in authority section is not listed in nameservers, which states
it does not have authorative data.
Thanks a lot.
Please see this dig:
$ dig +norec dev.game.yy.com @202.96.128.166
; <<>> DiG 9.4.2-P2 <<>> +norec dev.game.yy.com @202.96.128.166

So, is 202.96.128.166 a lame server?
Regards.
