Yes that would be correct, leave the pan and tilt handles alone (lock off the roll handle and don't touch it at all) and just orient the camera using the ball head.
It's the polar axis of the Polarie/Astrotrac that you need to align so the camera orientation on the ball head doesn't matter.
As Greg said, it's going to be pretty rough depending on the controls your tripod has and how small adjustments you can make to them.
I'd be interested how good you can get it, good luck!
