Hi JD,
Guys having to loosen the cable to get the clutch to bite again does make sence, let me try and draw a diagram.
Health clutch cable and clutch plates below;

......^cable^.......^plates.^gearbox
If the plates are wearing thin, then as the springs within the clutch pack push the clutch plates closer together to try and get it to bite, then it pulls on the clutch cable to the point that they are so thin and warn out that they are suspended/hanging by the clutch cable as below;

Those hanging plates in the middle of the diagram above mean the plates are spaced and slipping.
Loosening the cable essentially makes it a little longer and allows the plates to press tightly together again.
