eccentric cam and ball joint to spindle angle

The ball joint should be nearly vertical when bolted up. It looks like its the correct way, and is correcting the angle that the pivot mounts are built with, but almost like it is too much angle???
I think if that were put on the driver side, the ball joint stud would be looking at the front of the car wouldnt it? You have the angle that the pivots are built with, and if you put that arm on the driver side, now the ball joint adds to that angle that the pivots are built with correct? Am I missing something??
