Dude, the second image from the ending it's not Rinoa's eye, it's still Edea's. Overlay a translucent copy of the image over the first image of Edea's eye in photoshop. It fits perfectly. It would also explain how Squall ended up back at the orphanage in time to see Ultimecia make Edea a sorceress. He tries to remember Rinoa but ends up remembering Edea and so ends up out of place in time.
