Parallel edges have the same color. The color shows which two places are swapped, as indicated by the triangle of pairs in the bottom right corner.
In the bottom vertex of an edge the elements on these two places are in their natural order, and in the top vertex they are reversed.
(Consequently, the bottom vertex of the whole diagram is completely in natural order, and the top vertex is completely reversed.)
