I think it happens for about everyone. My current theory is that with the fat redistribution in areas of the face, you get the softer appearance, but in other areas you where the fat hasn't or won't accumulate that we still carry a similar reflection from that angle, and we see our all too familiar face. However, the fact is that it has changed from multiple angles. It's just the angles that catches our face with the solid bone structure that you see the old you because it is familiar.
