This causes a critical reduction in the angle of attack and a corresponding loss of lift causing the helicopter to descend faster and faster up to rates of 6000 feet per minute.

SWP nearly always happens close to the ground and once in it, there is no recovery. You have no spare power to reduce the rate of descent or to increase airspeed to increase lift and fly away.

SWP nearly always happens close to the ground and once in it, there is no recovery (insert suitably large number like 99% of the time). You have no spare power to reduce the rate of descent or to increase airspeed to increase lift and fly away.

The helicopter will very quickly develop a high rate of descent. The pilot increases collective to compensate but quickly finds that the engine cannot produce enough power to maintain lift and power the tail rotor which is also working harder since you increase the torque by increasing power. It is possible to simply run out of power. If the pilot is lucky, they will be unconscious and found with the collective lever buried in their armpit.
