The problems relate to focussing on distant objects and shooting wide open - this is not something which is called for, so normally goes unnoticed until or unless tested specifically. Compare with manual focus on a distant object and you will probably find that the AF has focussed in front of the object. Well documented on dpreview and I think pretty much everyone found to their surprise that it was evident, but the conclusion was that under normal shooting conditions it is not that significant.
