lol, this is not a mistake. Its called targeting demographics. Using Dart or atlas ad servers you can target an ad to just about ayone and Sony paid good money to Gamespot for them to target MS visitors.
Also, this could be a retargeting ad...for example, if the surfer went to the PS3 page first, and then went to the 360 page...that ad exclusively gets called to remind the surfer..."hey, come back...we love you"
