Dynamic roll over
crab
I agree with your practical comments, but:
I still don't like the reference because it should at least show first that the max cyclic counter angle is in all helis (I know of) smaller than the angle between vertical and COG-skid line.
For me it is a geometry question. Force only will explain how fast you roll.
The reference keeps center cyclic...
I would use increasing counter cyclic in the drawings.
