Auto Awesome Blooper or Optical Illusion?

I took these photos of my footprints in the sand late yesterday afternoon. The Auto awesome HDR* photo on the left is taken looking away from the sun and the HDR* on the right is taken towards the sun. The effect is not as noticeable in the single images, but is very apparent in the google+ autoawesome HDR*(which by the way was not intended to be created and sorry about the annoying solarizing-style effect on the wet sand in the upper right of the left hand image, my interest in in the footprints which appear inverted)
 

Do the footprints on the right hand side look inverted?
