What do you mean "reference points"?

An example would be the point in a technique when a strike has been delivered. At the "end point" of that execution, if a snapshot were taken of your position, you would be in a particular stance.
Right before that, and right after that, you would not. The stances are points in time, and points of application, which ties application to timing.
