Catapults can fire without setting up

Is this a bug? I can fire my catapults on the same turn as I tell them to set up for firing. I first tell them to set up and then right click on a target. They fire without having to wait till the next turn.

I think this may be intended.

Siege units have two move points.
So, at the start of your turn, the first MP is used to set up, and the second MP is used to fire.

That makes a certain amount of sense. I guess I wasn't clear on what "setting up" actually meant and all this time I had been waiting a turn before firing the catapults.
