At the pot side, the conductor goes to its designated lug, the braided shield needs to be untwisted from the conductor insulator and then twisted back up, so it forms its own wire. Then that braided shield (now a wire) goes to ground. So the "two wires" are the center conductor and the braided shiled.
At the tube side you only use the center conductor to its destination. The braided shield gets cut back and Is Not Used. If you have some heat shrink tube, you can make a sanitary/safe off to cover any little bit of braid that might be exposed.  The idea is to make sure that the braid does not make any contact at the tube side of your connection.
Does that make sense?
