What I meant, was that in the zero g condition the rotor system is unloaded and as such was not completely responsive to cyclic input. It is true, in this situation not only is the helicopter free floating in space the pilot is as well. It is almost as if it were in orbit like a satellite. Until the pilot can get the rotor system under positive control by gently bringing the cyclic stick rearward the rotor is not under control. When the rearward cyclic takes effect, the pilot can then take corrective action by applying some left cyclic to counter the right roll. If in the process the pilot introduces right cyclic and adds to the right roll caused by the propeller effect of the tail rotor the helicopter will imediatly increase the rate of right roll.
What you said in your last paragraph about doing a diving right roll with a very large >> 60 degree bank is a viable alternative. Other pilots described this same maneuver on this thread. However being able to do it depends on two things both being equally important. The first is APTITUDE and the second is ALTITUDE. The ability to perform the maneuver and the altitude necessary to correct for the dive.
The way the POH addresses this matter is to not introduce right roll during zero g recovery and to never introduce left cyclic to counter the right roll when pulling back on the cyclic.
If you looked at the diagram you can see that the pilot must have situational awareness as to where his cyclic is in relation to the rigged neutral position. In accordance with the diagram it can be shown that it is very easy to introduce right or left cyclic during recovery from zero g.
Regarding why right cyclic is bad, please read safety notice SN-11 in the Robinson POH
