And I read that statement - maybe I need new glasses - as a limitation applicable to forwarded lookups not resolved by the DNS master / slave zones locally available. So in my understanding it doesn't cover what I want.

Actually no, it's the 'queries in progress' that are received from
clients - i.e queries received by named in its role as a recursive server.

The configured limit is on how many concurrent unique queries that can
be kept track of at one time so that named can respond to the original
querier appropriately.
