When the car is on the ground after being driven its what I call "settled ride height". Where the bushes have stretched into their normal position and the wheels have cambered out.

When you lift the car the bushes contract, for lack of a better word, and when you drop it back on the ground it stays in that contracted state until you roll the car back and forth a few times till it goes back to normal. It will also normally leave the car sitting higher until you roll it as well.

You might notice when you jack the car you can hear the wheels scrubbing as little as they pull back into the car as it lifts. The other most noticable is when you lift the front end and drop it back down the wheels will appear to have positive camber and the front end 20 to 30mm higher than normal.

If some of your bushes are getting into the fubar stage then yeah, it could ruin your alignment when the suspension is at full droop. Specially the rear inners when they get old.
