If you look at the animated GIF you can see the two shapes morph into each other almost perfectly, they are similar shapes in the same position.

The next comparison is of a small feature shown in both faces below. If you watch the animated GIF these morph into each other.

The next part is where the two faces join. The right hand part is shown in red to make it easier to see. This line is also very close to where the right hand face joins. The line extends up from the top of the nose line in both cases.
