Not sure how many times it needs to be repeated, but apparently at least one more time... the angle of the line(s) has no bearing on whether or not the boat is righted. Over the hull, under the hull, using a righting pole, holding with your hands, holding with your harness, or holding with your teeth, it makes no difference. All that matters is the horizontal distance of your center of gravity from the fulcrum (which is the center of bouyancy of the lower hull). How you get your CG into position only effects the reactionary forces on your body (your comfort level), it does not effect the righting moment applied to the boat.
It is just like the teeter-totter we played on in elementary school- the rig is at one end, you're at the other end, and the hull is in the middle. Weight times horizontal distance.

If you had a proper diagram in front of you it would be obvious that your weight is 18 inches or more further out when you use over the hull and pull with your hands from above your head, which is a handy increase in leverege, in all of Scarecrows diagrams there is no righting moment at all because all of the people pictured are laying in the water.
