Reverse the order of what? ArcTan of one argument has only one argument and how can that be reversed? What has two arguments is the coordinate specification {x, y} and they are not reversed in ArcTan[x, y]. It is the one argument form ArcTan[y/x] that seems poorly designed and would probably only be used when one knows the quotient and not x and y - so there wouldn't be anything to reverse.
