Why even make the distinction? Why aren't the rescue swimmers trained to ride the hoist down? Use the technique appropriate for the situation. Our PJs use a climbing harness to connect themselves to the end of the hoist and carry a strop down if that's the plan. Granted we don't use a basket, if the survivor isn't capable of riding a strop with a PJ 1 foot away, they get strapped into a stokes litter. Maybe I'm just missing the point of the original poster's question.
