GetWorldManifold Question

I am trying to use GetWorldManifold(out Vector2 normal, out FixedArray2<Vector2> points) to get the point of impact.  The question I have is which of the points in the array do I use to get the contact point.  Is one point for Fixture1 and the other for Fixture two?  Do I have to do something with both points to get the true contact point?  

I have also heard that you should use the afterCollision event from the body fixture to get the manifold or else the points and normal could be 0.  Is this correct?
