There is no reason why a diver should need rescuing by another diver. A diver should never become so narced that he needs the assistance of another diver to return to the surface. Why would you need a redundant air supply? Why would you use all of your air supply? Why would you get to a point when you need rescuing? , why would you need more than 2 arms or 2 legs, in fact 1 arm or 1 leg is enough for some divers! The only reason a diver may need assistance is a medical emergency, heart attack or something. But that has nothing to do with diving practices,
