Because the first one *did* answer, just not with the answer that you
wanted.  The second server is only going to queried if there's no
response from the first.

And then, you'll probably find, that every time there's a query, it
always asks the first listed server, first.  Logical, but up to a point.
If the first server hasn't responded once, within the ample amount of
time before a timeout occurs, it's probably not going to answer next
time.

So, if you ever find that name resolution keeps on taking an absolute
ages to resolve, chances are that your first name server doesn't work.

Another OS doesn't do that.  If the first one doesn't answer, and the
next one does, then subsequent queries go to the same server that
worked, last time, rather than crawl down the list, again.

I don't think Linux works like that, but it's ages since I messed with
failing DNS server to remember.
