Caroufredsel pagination does not slide in the natural order

[julienmru]

Here's the demo implemented with only two slides: http://www.cahri.com/tests/caroufredsel.html

Each time you go from slide 2 to slide 1 it scrolls the image from left to right instead of right to left. Going from slide 2 to slide 1 should have the same behavior as the Prev button which is more natural on a user's perspective.

Any idea how to fix it?
