I guess that is for the Terminal to start the main Mac (host) in single-user mode, not the virtual Mac (guest). Right?
Yes, that is done in a Terminal.
But you can also start the main Mac (OS X 10.8.3 in my case) in single-user mode with Command S at rebooting or cold booting. So, what is the purpose of the Terminal command?
Well, sometimes it hard to use the Keyboard when booting a Virtual Machine, timing can be an issue. So if one can still boot to a normal Desktop and they what to boot to Safe Mode or Single User Mode then using the Terminal can actually be easier and faster then trying to set focus to the VM Display and press the appropriate key sequence at the appropriate time to invoke the required action.
