A bit misleading of a title since they are estimating how many will violate the rules. 50 characters seems like a really long name but good to know "Very best app you could possibly download ever" wouldn't break that rule.
I'm pretty sure the goal of the 50 character limit was to keep it possible to have descriptive names that go beyond a word or two, but prevent extreme keyword stuffing (ex. Car racing game - race cars, trucks, bikes, people, animals, temples, and run like the angry bird, or go with pokemon). Obviously not a real app, but I've seen a lot worse...
