Look at it another way.
Most of us have an endorsement on some kind on a teetering head machine. We know that if we let the machine head towards zero g (or enter head banging mode) the rotor disk is then free to do as it wishes and often wants to bump the mast and detach itself.
When the g's are decreasing in forward flight most of us instinctively load the rotor with cyclic, not collective - it's ingrained, and it is regardless of what type of rotor head is fitted by the manufacturer. Even those with FW endorsements already know that secret
