Two different folder paths are created for the same image: one for the image used in the animation and one for pivot properties.
Create a new animation.
Adjust pivot properties of an image.
Add the image to the timeline.
Save.
Adjust pivot properties of image. * Note that the values you set before saving are reset.
Set a new pivot point.
Save.
Note the slight differences in pathing. First folder refers to the first image placed. Second folder refers to new pivot changes made. If any new images are added, they reference the second folder.
