I don't see any problem at all, it is natural. You may be wondering why. 
Well, when you do an nslookup or dig upon a full-qualified host, you are using 
standard resolving facilities for your queries, in the first case you are 
using your resources to make nslookup query on either of your /etc/resolv.conf 
nameserver records and they do the job. On the other hand, for a dig to a fqdn 
you ask your NS directly to do the job, it is easily done because you have 
either the path to resolve a fqdn (with hints) or it is authoritativ on your 
NS. In this case you also have the NS search based on your nameserver records 
on resolv.conf. In the third case, you don't have a way to query your dns nor 
it has any way to guess you are looking for a name inside your own domain. 
Still using your resolv.conf for finding your NS but nothing more. 

Hope I explained myself!
