I was thinking about two different applications.

One lack of good ground with the table due to dirt or whatever. Attach the extra cable and your good to go. A little help from a friend so to speak.

The other is if you are using some type insulating material between the work and the table such as rubber tires on a lawn mower being repaired. No use disconnecting the "good ground" to the table. Just add a jumper.

My concern was the way the electric flowed and if it would effect the weld or the welding machine. I never did understand how 4-5-or more welders could be connected to a common grounding clamp and one lead going to the work where several stingers were being used. (Large fabrication with several welders working at the same time). When ask how the electric found it's way back to the right machine to complete the circuit, I was told not to worry about it. (grin).

Again the jumper is NOT made from 18 ga lamp cord, but made from REAL welding cable, using REAL welding clamps.
