Be careful with that statement... not everyone can do that because at some point, the lower arm will straight up contact the wheel from too much spacing.
Also, you don't necessarily have to have the ball joint located beneath the inner pivot for the suspension to gain negative camber under compression. As long as the angle between the imaginary line formed by the upper mount and ball joint and the imaginary line formed by the lower arm inner pivot and ball joint do not exceed 90 degrees at maximum, you will still get negative camber gain under compression.
If you have a pillowball upper mount camber plate thing, that means where the spherical bearing is... so if you moved it in for negative camber, that changes the angle of that line a little bit.
