In my case, my computers will end up on that screen in two cases.
The first is my desktop, without a TPM, which will ask for a BitLocker password. In this case, if I'm not fast enough, it will shut down the computer.
The second is my work laptop, which I usually expect to reboot or otherwise am around when it ends up there, in which case I'll usually type in the PIN quickly enough. However, I expect it to have a similar behavior as the first case, although I haven't tried.
But the reason I know this happens, is that I once left this PC attached to my 32" screen next to my bed, and it woke me up at night. I just went and forcibly shut off the thing.
