It’s the same, just reversed, you say…but it’s really not the same.
Clasp your hands together– either your right thumb will be on top or the left one. Clasp your hands together 1,000 times and whichever thumb started on top will be so every time. Automatic. Your body-mind decided which one would go on top without asking you first. Now, try reversing it. Strange. Awkward. Your original thumb–left or right– and all the rest of the fingers will be itching to get back to the ‘right’ sequence.
As for what we see, it’s hard to be sure if an image is inherently ‘right’ in one direction or just what we’re used to.
