Correct, the swirl pot should be full but the expansion bottle finds it's own level and will dump anything in excess of that.
Concensus seems to suggest that half way full or two inches off the bottom is common but my Griff runs perfectly with just about an inch in the bottom.

Just be concerned about the car running at the correct temperature and that it's not losing water rather than how much you're putting in and what the levels are.

thanks
My 450 seems to be about 20mm down from the top of the swirl pot is this ok?

Checked mine this evening after a week of running, post last weekends radiator change.

Swirl pot is about 1/2" below the top.
Expansion tank is about 1-2 inches from the bottom.

This is exactly how it used to be before the previous rad started leaking, so I'm happy it is right (Caveat; for my car).
