Without a diagram it's kinda hard to explain, but just think about what defines the scrub radius, then look at how the angles were changed and what that does to the scrub radius.
Increasing SAI (adding camber at the upper mount) will move the scrub radius in the negative (outward) direction, adding camber at the knuckle will move it in the positive (inward) direction.
My last post was wrong about all camber moving the pivot point outwards, forgot what the knuckle alignment looked like when I typed it.
