Yes it's a bit weird. Think of it like the root hints but for other zones:
i.e. a hint zone configuration in a recursive server tells named that
instead of using a referral from the parent zone to find the name servers
for this zone, use these configured name servers. However the name servers
at the zone's apex can override your configuration.

If you use static-stub instead, your configured name servers override all
name servers for the zone that your name server might receive.

The difference with forwarding zones occurs if there is a delegation point
below the zone you have configured. With a fowarding zone, named expects
the target name server to do recursion, so the target server will deal
with following the referral and resolving the final answer. With a stub
zone, named expects to get authoritative answers and referrals to child
zones, and it will do its own recursion to resolve the final answer.
