This setup will not work reliably: the target forwarding server has to be a recursive server, since the forwarding client will expect it to do full resolution of the query - following delegations, etc. I expect it will have funky interactions with DNSSEC validation (e.g. chasing DS records) but I have not experimented with this myself. Also, you should never turn off the `dnssec-enable` setting, since that prevents BIND from doing the right thing with RRSIG/NSEC/DS records. This will break downstream validation even if the server is not itself validating - that is, if you turn it off on an authoritative server, it cannot serve any signed zones.
