 after loss of power, by lowering the collective lever to reduce blade pitch, the rotor speed will drop below a recoverable RPM and the rotors will stall. In that case it will end the same way as this demo.

Not much point in that test other than to see how it breaks.
If pilot does not react fast enough (usually within a couple of seconds) after loss of power, by lowering the collective lever to reduce blade pitch, the rotor speed will drop below a recoverable RPM and the rotors will stall. In that case it will end the same way as this demo.
As Frank said, in a real world scenario after loss of power, if pilot lowers collective pitch quickly, he can autorotate and with sufficient altitude and with a suitable flat landing spot available, it's completely survivable and may save machine without damage.
