Exactly. Even if you're not very good at sending or receiving Morse, you will have a distinctive "fist" - just as distinctive as your handwriting or the sound of your voice. As you get better, your speed and accuracy will improve but your fist will sound just the same.
Machine-sent Morse is as weirdly unintelligible as synthesized speech, and for much the same reason - the inflections are missing or wrong.
