Dig will try every entry in resolv.conf. It behaves this way as it is
a troubleshooting tool. This is not how the system resolver libraries
behave, nor is it how they *should* behave. Once a DNS server has
responded that the domain or host does not exist, it would be silly
for the client library to assume that it's incorrect and move on to
try two or three other DNS servers just to be sure.
