An abundance of anus hairs in my case. Top to bottom (back to front) aligns the hairs in such a way that they don't end up stuck in the anus hole, which I've experienced leading to itching and irritation. However, at least one front to back (bottom to top?) is mandatory in the middle of the loop for increased cleanliness, as either the skin folds or anus hairs obscure some fecal matter that the top to bottom (back to front) directionality doesn't pick up.
