People take away what knowledge they can USE. If they only remember the cool/gross factor, at least they have remembered the event. That means if they need the chemical reaction later, they can describe its effect and look up the details. Students with a deeper interest in science will remember more from the beginning. But maybe the cool factor will get someone interested in science who wasn't before.
Besides, salting the legs doesn't interfere with other uses. You could still eat them, or dissect them to learn the muscles, or try different chemical baths to see if anything would recharge the muscles and make them twitch again after expending the latent charge.
