It shows honesty when you admit you are in error. To dispute an allegation that is not correct is one thing. To commit something that is not right is another. It is better to admit the error and move on. When people bring it up, the sting is not noticed so much because it is "old news." Their attitude becomes "We know that. Can we go on?"

Even if he is right (which is questionable), how many people believe he has their interests at heart? A dedicated reformer has a way of reaching out hearts and minds. Part of their tool kit contains the ability to admit error.
