Are you sure of that???
Internet nameserver resolution does not know a master (primary) from a slave
(secondary).
It uses the one that answered faster.

correct, however in many cases ns1 / ns2 are in the same colo or even on the same box (yes I know it is better to have them separated geographically, but that requires two boxes or a peering arrangement with someone else, and I am assuming this guy doesn't have that, hell why even stop at two nameservers...) and for that situation I have found that reversing them makes transitions smoother
