To those who suspect old code or premature optimization, if you read the comments all EA sports games apparent cap out at 255 points. It's an intentional throwback. When he did it in one quarter he triggered an Easter egg, a "false start".
I'm not sure I would call a false start an easter egg. It is a fairly standard penalty called all the time in real life games. The reason it was special enough to mention in the article is that he had specifically turned off penalties for the game.
