Sure but.. :)
From the top view profils are absolutly similar (open start/ end)
and here it's very easy to select the little arcs for un rotate
Rotates are made on the profils after a sweep for any esthetic reasons :)


but if you have some different figures and thousand of it it's no easy
With the Start Open Curves script we can see what are the curves inversed between them
because "points" are more near them or not
