It happens, and has happened to me while moving it manually, especially if I stop and let go abruptly. If I do it gently, it’ll stay in place. It also happened a few times when I didn’t screw the Z coupler properly so it just spun out. The weight of the print head along with the general resistance and stepper rotor magnetic resistance should be enough to make it stay still, and I assume it stays still as well when you turn off the printer. Or does it just crash onto the build plate?
I don't recall it ever crashing, with the printer on or off. I can test explicitly what it does when the printer is off, when my current print finishes
