Chopjock - unless the nose is pitching down - the SN specifically says ' If the helicopter is still pitching forward when the pilot applies aft cyclic to reload the rotor, the rotor disc may tilt aft relative to the fuselage before it is reloaded.'
As I said earlier, unless you are zero G, you will have some cyclic control but at the lower end of the scale it will seem less effective so judging 'gentle' or 'a little' aft cyclic might be very difficult.
If there is no nose down pitch then gentle aft cyclic should work.
The rapid entry to autorotation is a problem if you push the nose forward - as in the accident I linked to and the other SN - in that case aft cyclic would be disastrous.
Jellicoe - the SN says that aft cyclic would combine MR torque reaction with the TR thrust - the TR thrust is producing left yaw and any application of lever would produce right yaw. It is the reduction in MR Torque caused by flare effect (moving the cyclic aft) that aggravates the yaw and thereby the right rolling motion highlighted in the SN.
