@Alan I don't really know why is this restriction. I was just asked for help to figure out this small part of a bigger problem.

comment Explanation and validation of point adding/doubling on elliptic curves
Thanks for the answer! I don't think it is a typo. One says lambda(x_3-x_1)+y_1, other says lambda(x_1-x_3)-y_1 , which is -1 times the first one. No typo or double typo.
