Leader line is used in most catfish rigs to help protect against the abrasive mouths of catfish, rocks, stumps and other items underneath the surface of the water that would cut or damage fishing line. Its extra assurance against losing fish (and tackle). The abrasive mouth of a big catfish alone thrashing on the fishing line can cause fishing line to break so that's why savvy catfish anglers add a catfish leader line that's heavier and more abrasion resistant than the main monofilament or braid leader line. Catfish leader line also serves as a “shock absorber” when a catfish strikes. This absorbs the force of aggressive strikes from big catfish. That shock absorption is important with mono and braid but due to the lack of stretch in braided fishing line you should always use a monofilament leader.
