From reading the description it seems like AAA used tests where there was a bend in the road and / or the pedestrian was moving across so they weren't actually in the path of the vehicle until a couple seconds before impact. These systems are going to be conservative in classifying potential obstacles as in need of emergency braking, as they should be - you don't for example want your car slamming the brakes because it sees a pedestrian on the sidewalk next to the lane you're driving on. That said, it should be noted that the Honda Accord actually did quite well in these tests.
