Why does my DCU command not auto reboot the workstations?

From what I can tell, it seems perfect but at the end it does not reboot the target machine it just completes updating and say a reboot is required. If "-reboot=enable" is specified, why is it not working?

C:\Windows\system32>"C:\Program Files\Dell\CommandUpdate\dcu-cli.exe" /applyUpdates -autoSuspendBitLocker=enable -reboot=enable -outputlog="C:\Temp\Dell-Update.log"
