||The Recursive Layering indicates a direct or indirect recursive layering.
For example, in a routine call layer diagram this shows a recursive call.
||moves the top right corner
||defines only the vertical position of the bottom left corner
||Put any recursive layering below normal layering connections.
This makes the layout clearer because element B depends on A, therefore the connection from A to B should
be above the recursive connection of B.
If you think of it as a routine call layering, you see that
the recursive call of B can only happen after routine A has called B.
