type forward with no recursive flag "rd -" --> Does it work?

When having one zone "windns.mycompany.se" hosted and handled by an
other nameserver (Windows AD) declared as:
zone "windns.mycompany.se" {
        type forward;
        forward only;
        forwarders {;;};

Rest of the zones exist on our primary BIND dns caching nameserver.

Client looking for "windns.mycompany.se" will have an answer because the
recursive flag rd (+) are stated and query will be resolved via forwarders.
When a resolver looking for same information, resolver will send
recursive rd (-), and the resolver will never get information regarding
zone  "windns.mycompany.se".

Shouldn't "Asking the forwarders" be prioritized before the "recursive
rd (-)" flag are taken into consideration? Otherwise I can't see how a
resolver ever will find information in the forward zone
