He seem to believe that valid XHTML will render the same in all browsers. If only it were so easy!
For example the Flash-trick that he talks about is just a script that writes the embed-tag through javascript. The only advantage is that the page now validates, since the validator doesn't execute javascript. The actual HTML rendered by the browser is still contain the embed, so obviously it will not render any differently.
Its just a pointless pursuit of validation for the sake of validation.
