I didnt understand his message since he said "that doesnt really apply to this game". Pretty sure this was not intended to be such a cameo heavy game. The mom, 2nd mom and sister are all original characters and who he used to use to advertise the game. As development went on, more and more celebs and cameos started popping up. Death Note was only really stolen from for its name and the magical beings, Sex Note isnt about writing down names or finding other Sex Note users, its about using a Notebook to cast spells and seduce women.
