An interesting point has been raised concerning the PC2e example on Pages 23 and 24 (take off with the wind through the Limited Obstacle Sector (LOS)) - when flown at night:

The pilot sits in the hover pointing towards the LOS (holding just enough yaw to keep within tail rotor limitations), applies the power then, when reaching the TDP/RP, rotates - involving forward and (mostly) sideways application of the cyclic.

As the pilot crosses the deck edge, there will likely be a loss of visual cues (inky blackness). The AH will be providing quite a complex and changing picture - certainly one that would be difficult to maintain if on instruments.

Compare this to the sideways procedure where: visual cues are maintained, the attitude is held constant and, at the TDP/RP control is transferred to the pilot-monitoring (already on instruments) to rotate into a continued take-off which - compared to the dynamic procedure - will be a much more sedate event.

Is this the exemplar for the sideways procedure, for the reasons stated on Pages 17 and 18 of the paper?
