I don't think that's implied. He said:-

Now I believe most uncut guys will find their foreskin is retractable by the time they reach puberty just because it happens on its own. You don't need to have been masturbating from childhood for it to happen. I didn't discover masturbation until I was 12 and had no problem from the start.
