Maybe because the flow of electric is neg to pos if you check his post you will see it has many circuits and a ground cover many. Not like a fuse line a few in line it wouldn't jump all over the system. A ground and cover many and rust and cause a lost of problems.
Conventional current flows from the positive pole (terminal) to the negative pole. ... In a direct current (DC) circuit, current flows in one direction only, and one pole is always negative and the other pole is always positive.
