To be correct, this statement should be
For ambiguities that do not reach or cross the poles or cross the
equator, the border away from the equator is shorter than border
towards the equator, making it a trapezoid.
Minor difference, but I think the protocol does allow ambiguity to
reach (but not cross) the poles, and the linear projection of this
would be a triangle.
