That's the way to do it.

Every request returns *all* of the addresses, with the order rotated each
time in round-robin fashion (you can change this default with named.conf
options).  Most applications either just use the first address in the
response or try them in order, so you should get the load balancing
behavior you want.

Look up "round robin" in the DNS & BIND book.
