Kidney AT II and contraction alkalosis

I understand the alkalosis part, because AT II works on the PT to increase the Na+/H+ exchange, so you dump off more H+ leaving more HCO3-. What I don't get is the volume contraction. If you are reabsorbing more Na+, wouldn't you reabsorb more water and have volume expansion?

I figured it out, the contraction is not related to the AT II, the contraction is because you are already volume depleted.

... At least I hope that is correct.
