Not that it's not true, it's just not clear. His description of camber is as if you were looking from the rear or front of the vehicle, hence / \. And if your caster is off, it could very well push the wheel forward or backwards.

Also, on some cars, the strut is mounted on the LCA, so it would be the angle of the knuckle.
