Absolutely correct Special 25, no inferred run dry time was ever intended when I was involved in AS 332L1 flight training.
I was lucky enough to witness the RUN DRY test on the L2 MGB at EC during a visit, also to view the MGB strip down after it had been completed. Enough to say the NF over speed shut down system worked on both engines and the ensuing leaking hydraulic fluid fire was extinguished.
Outhouse.
