I think the point Franz is trying to make is that the more focused punch would apply more energy to that one point as opposed to spreading over a larger fist's surface area. To wit, a Lalafell's punch to the jaw with the same force would theoretically be more likely to break that jaw than a Highlander's because all that energy is more concentrated on that one point on the jaw. This is, again, assuming that both are hitting with the exact same force, which a Lalafell may or may not have to put more effort into.
