That is 100% correct!
That doesn't say that said aircraft cannot endure inverted flight for a very limited time.
To be outfitted for inverted (neg g) flight the engine must get metered fuel AND oil-pressure during the inversion.
Afaik all piston drive AC during that time only could endure neg-g, some better than the others.

Many people do not know, but the DB 605 operating instructions also write, that prohibited the long inverted flight, because of the lubrication system.
