Nope. There are many props out there that have the letters/numbers on the back of the props. i.e. putting the letters forward applies to APC props but not to props made by Multiplex. Everyone should disregard any letters or numbers anywhere on the prop and follow the picture below to make sure that the prop is oriented correctly.
