three commands is invoked.
--reboot
Reboot the machine, regardless of which one of the three
commands is invoked.
-f, --force
Force immediate halt, power-off, or reboot. When

contacting the system manager. See the description of --force in
systemctl(1) for more details.

NOTES
These commands are implemented in a way that preserves compatiblity with the original SysV commands. systemctl(1) verbs halt, poweroff, reboot provide the same functionality with some additional features.
