Indeed...however even if you assume that a few of the 11MY cars had the older bearings the trend is still not showing any improvement for engines with the new bearings with the larger clearance. Especially when you take into account that the average mileage at which the 2008/9/10 cars fail is around 40k miles while the 2011/12/13 cars are failing at an average of 24k miles. If anything, increasing the clearance has made it worse.
