This isn't the normal shutdown, only the power-has-failed mode.

IIRC, this is a response to line power failure and UPS battery drain.
With at least some model UPSs, if you shut them down like this, when
line power returns, the UPS automatically turns back on.  If you have
the computer configured to auto-turn-on when power returns, it'll boot
back up when the UPS turns on.  The idea is the system runs as long as
possible on UPS, and then automatically comes back on when line power
