Is the main DNS server also a caching server for your network?  If so, 
then when someone outside your network queries it (let's say for 
www.av.uni.edu), and the answer is already cached because someone inside 
the network made the same query, the main server will answer the query 
rather than providing a referral to x.  Since it cached the answer from 
an internal view, that's what you'll get when you query it from outside.
