When helicopters lose power they just fall. If the rotor head isn’t decapitated then when you get ejected sideways there’s s no zero chance you’ll be julienned on the way down.
It’s why the most (only version currently in operation) common method of helicopter ejection severs the head or blades while it’s still rotating so it/they spin off and hopefully away and then the seat rockets away.
Your first sentence is wrong. Stop explaining things you don’t understand yourself.
It’s a fact. Helicopters in general do not have the ability to glide to a landing, they can auto rotate if the rotor is still moving and has enough momentum. If the rotor stops or detaches helicopters fall…
“if the rotor stops” luckily in this universe we have conservation of motion so the rotor doesn’t typically stop in flight
Sure though, were it to detach the helicopter would fly like a brick

Any modern heli design will autorotate down. It’s not exactly gentle, but it works.
Autorotation relies on one main thing, air being forced past a freewheeling rotor… Air that is being forced past because you’re falling.

Notice the immediate loss of attitude? It’s because they’re falling, unlike planes which can generally glide after an engine failure.
Specifically we’re speaking about helicopter ejection which in most cases means total loss of power or control or both. The only known helicopter eje tion seat(to me at least) to operate currently in modern combat is the ka 50/52.
One like this one which happens to eject and notably falls like a stone.
The KA-50 and -52 destroy their rotors when the ejection seat fires, as shown in this simulation. That’s why the helicopter drops like a rock after the ejection seat fires - the blades can’t autorotate if they’re not attached.
Assuming the blades are still attached, the helicopter will autorotate down even if it is completely unpowered. It might lose some altitude initially, but like you said once the air is moving over the blades fast enough for them to spin they will do what they were designed to do.
One thing helicopters and planes have in common is that if they fail too close to the ground autorotation/gliding won’t help. Helis are generally more dangerous than planes for a lot of reasons, the biggest one being that they spend more time in the most dangerous phase of flight - landing.
