As the name says it is a back-up speed scale replacing the standard speed tape. The red-yellow-green tape moves in the same sense as the standard speed tape. There is a target speed indicated by a green area and triangle.

Numbers have simply been replaced by colors. How is that confusing or counterintuitive?
