Does that at all make sense?

Main rotor head design vary greatly, as does blade design. In Fast Freddy's picture (very cool, btw) you can esy see that the Cobra shared the "teetering main rotor" design with the Huey.
That design was susceptible to mast bumping.
The H-60 main rotor head design is not susceptible at all to mast bumping.
There are also rotor head designs, like on the Lynx, that allow for aerobatics.
So, it depends. There are rotor systems that are more like to have "retreating blade stall" characteristics than other designs. It is all a trade-off.
