The FAI clearly agrees if the statemnent attributed to their president is true,to whit the only way it can be a true helicopter is for all the dynamic lift and power to go through the rotor sytem (apart from engine exhaust Cfoskey).
I think they said
power-driven rotor system
, nowhere do I see that all the power has to go through the rotor system. If this is true, then a conventional helicopter is not a helicopter because it has power going to the tail.
