Because it seems he lost him arm around the time he learned to fight, it's likely he never had a chance to learn about his ability until later. He could've also been knocked out of his territory or he voluntarily walked out of it because he simply didn't know. I'm guessing most of his scars later were from testing out his territory range but that's pure speculation at this time.
