"Command" as control structure?

[Peter Bogdanoff]

I see that “command” is a synonym of “on” in LC script.

Is using “command” rather than “on” a purely style preference?

I see in the old LiveCode dictionary:
	The command synonym, along with the ability to declare private handlers was added in LiveCode 2.8.1

Why? Is this something to do with the message path?
