Right. The average of a number of samples can exhibit characteristics not present in each sample, and so it does here.
One characteristic often considered attractive in a woman's face is a rounded soft jawline. The average of a large number of samples will tend towards rounded soft features, just by the nature of averaging which blurs together any large outliers.
A starker example: People who weigh 80 pounds and people who weigh 240 pounds are both considered unattractive. But average a bunch of each and you get a perfectly attractive mean or median of 160.
