Well, Soong was a very old man at the time of TNG, and the image on the cover is of his younger self. Make of that what you will.
The image is actually from a vision of Soong that Data has in a dream. http://de.memory-alpha.org/wiki/Noonien_Soong
Yeah, I know the page is in German.
The English version doesn't have that image from birthright.
