Lower collective as you apply aft cyclic to prevent ballooning; pedals hold heading.

Ballooning, rotor overspeed, heading wander, tail/tail-rotor strike in the nose-high attitude.

They build the coordination/flare timing used in the autorotation.

Immediately lower the collective to preserve rotor RPM.

Fly the POH autorotation airspeed; keep rotor RPM in the green with collective.

RPM tends to rise in the turn — manage with collective; roll out aligned with the spot.

You sink/run out of rotor energy before touchdown; too low = no time to cushion.
