The following is my opinion as a member participating in this discussion.

Recreate a similar skinny person in a pano or I call bs.
In an automatic panorama, the software tries to join the images given to it, looking for similar features in adjoining images and using those features
common in two photos to join those two photos. It may (I don't know if the Iphone software does it) then try to adjust the adjust to the type of lens,
as an wide angle lens creates a bigger distortion of objects that are closer to the lens.
Creating a panorama without any moving objects in the scene is easier, but when one or more objects are moving in the scene the result is that those
objects appear in different positions in consecutive photos, so, when the software looks for similar points in both images if finds the object in
different places and may
be confused by it. Some, when detecting what appears to be a moving object, try to remove it from the final image, but
for that they need to "see" what was behind the object, and, if they cannot find enough area to cover what was behind the object then they (usually)
leave the object where it was, but may consider the background as the main target of the photo and not bother with distorting the moving object.
I that's what happened in that photo, the left (the viewer's left) side of the person in the photo was captured on a photo, and at the time that part
of the person's body was farther away from the camera, resulting in a thinner arm. On the next photo(s ?) the person wasn't exactly in the same
position and so the software gave priority to the background, not bothering with the moving person. As the person's left side was closer to the camera
it appears bigger than the person's right side, but as the software was ignoring it it didn't try to correct that distortion, worrying only with the
distortion of the background.
To try to show what I mean I took two photos of my left hand with some buildings in the background, giving the software a nice grid to join the photos
together. I moved my hand a little to my right and closer to the camera. This was the result:
Resulting panorama, created with Microsoft's ICE.
As you can see, the software decided that my hand was in the way and, instead of trying to recreate it, it worried with recreating the background, and
so removed my thumb. I can guarantee you that I still have it, and I even used it in writing this post, although only to hit the space bar.
PS: as I don't have an IPhone I did this experiment with a Samsung WB5000.
