Sounds like just semantics to me.
I stand to be corrected, but I think Lu's saying that cyclic pitch changes can't be made on the rotors in the fore and aft sense, and therefore it would technically be wrong to say that pitch controlling is done 'cyclically'.
However, in any helicopter I'd call that stick between my legs (now, now) the cyclic, and I'd be extremely surprised if a Chinook pilot can't pull back on that and make the aircraft flare, in autorotation or not.
If you can pull the nose up, you can change the relative airflow into the disc and therefore get flare effect.
Right or wrong?
