Try adding "+norec" to the dig command to disable recursion by the server:
    dig +norec -t ns <name> @<server>

That will get the NS records as known by the parent above the delegation cut, 
instead of the NS records as known by the child below the delegation cut. 
Differences in those sets can sometimes be, shall we say, interesting.
