Comment(by remic):

 Hm in my opinion it is an error.
 In no case should you have the same walk by walking forward or backward.
 Now if calling the function for +X and -X gives the same result (except
 for isolated edge).

 It is the case here,
 because whatever the sign you always end up turning in the same direction.

 Cheers,
 Rémi-C
