What happens is that PowerDNS hands off recursive queries over TCP
directly to the recursor, expecting that to get back to it should the domain
be hosted locally.

For UDP queries, pdns short circuits this process by checking its internal
database first.

Not quite optimal, but this has never been a problem.
