However, when we do that same analysis with the images that I previously overlayed, we get a much different result:
Now, the alignment is much more similar. To get such alignment between the two images of "the model", then the left image has to be skewed and stretched. I didn't have to do any of that with the right image and the yearbook picture. Reasons for the differences in all these pictures can be accounted for by camera angle, focal length, facial expression, time of the month, etc. The other thing that hasn't been accounted for is that SAD's high school picture was most likely retouched, while the other images do not look like they were retouched.
The bottom line is that nothing here rules out the model (or the right model) from being the same woman as in the high school yearbook picture. All I know is that when I superimposed one image on top of the other and vice versa, the alignment was uncanny. If I could make an animated gif, I could really show well these images line up by sliding the opacity back and forth.
