No, nslookup will, by default, append the default domain (or elements of 
the searchlist) if the initial query fails. You can inhibit this 
behavior by appending a dot to the lookup argument.

I think you're confusing cause and effect here. I'd be more likely to 
think that the appendage of the default domain is because of the 
timeouts, not the other way around. And why would you expect 
"mydomain.com" queries to be timing out anyway? I assume "mydomain.com" 
is supposed to represent your own domain -- is it misconfigured on your 
nameservers in some way? Why don't you post the *entire* "-d2" nslookup 
output -- or, even better, "dig" output -- so that we can see what 
actually happened to your query?
