Yes it does. It just doesn't all get answered from the one zone. Both of your
public servers, chyron and mercury, contain both zones. A non-recursive query
to either of them gets both records in an authoritative answer.

There is no need to configure recursion on your external authoritative name
servers. Other name servers will not query them recursively anyway.
I continue to fail to see the problem that you're trying to solve.
