It's simply going to cover a bigger surface area thus distributing the power rather than concentrating it.
It also means that to get around the gloves you are going to go longer with the hook thus opening yourself up more. You can go long and be more accurate with the palm down because you are trying to land your knuckles to establish the power line. After all, the desired aim is to rattle that chin isn't it.
