OK - a no-power full-down. On the descent there is little need for changes in T/R thrust once you reduce the initial pitch of the T/R (right pedal). However, if the helicopter is out of trim, the ROD will be a lot higher, result: more inertia to arrest with the flare.

If you keep the left pedal in at cruise position, you may not be able to maintain adequate control (depending on how much power you were pulling when you entered).

When you flare and start changing RPM/pitch, the mechanical drag of the transmission will drag the nose of the helo in the same direction the main rotor is turning, so you need to increase right pedal to keep the skids aligned with ground track. If you are doing a zero-groundspeed touchdown, the yaw isn't so critical, but if you are running it on, it might just be.

So that's why the initial answer!
