Just as a disclaimer/warning: That script will work best when used with actual animated geometry, where the vertex structure is known and the position of each vertex can be tracked down on each frame.
With the pointcloud you'll get from PositionToPoints, there are no "vertices", and each point has no correspondence in previous or later frames. I don't think you'll be able to get the animation of a certain point in your cloud, mainly because each point only exists for that one frame, if that makes sense. If your cloud comes from an animated creature / object, I think you'll be better off exporting actual geometry (even if it's a lo res proxy) to do that.
