I think if that was the intent of the note, then it would also imply there was active engine TQ management outside of the transmission TQ limits considering the note states engine only protection.
I can recall doing topping checks in a 212 once, where I could not hit the Ng stop before reaching ITT limits. I stopped trying at 10,000 ft!
I always preferred performing the topping checks on the ground whenever possible, however, not all aircraft would permit that method. In flight topping could become interesting especially when at the moment you record the rotor RPM droop the engine not under test experiences a governor failure and everything gets a bit exciting.
