Yes.  A server won't forward if it's authoritative for the domain.

Do all the administration on one server, and configure the other one as a
slave.  Or use separate domain names.

Note that having both of them forwarding to each other can result in a loop
if someone tries to look up something that's not in either of their
domains.  I'm not sure if BIND checks for the case of forwarding back to
the same address it received the query from.
