Wires from ground near magneto to points box

This photo is from a Briggs 12 HP engine behind the magneto. 

What is the purpose of the 2 wires going from this ground stud to the point box?

If I remember correctly (been awhile since I've had tin off), the wires that go to the points box are connected to an insulator stud, not a ground.  One wire goes to the points (which grounds the wire intermittently to make spark) and the other to the ignition switch to stop spark when continuously grounded.

If that stud is grounded (by rust or other failure) you won't get spark.

That is the setup on my 10hp Briggs - isolated connector from ign. sw. to points.  I think PhanDad nailed it if that motor uses a similar concept.
