Neither, really. Of course you can always say that the force F1 stop
at A and after that it is another force. But that other force is a
continuation of the force F1 and is there only because the forst F1
was at A. But because all effects of the force F1 don't arrive to
other points at the same time the force at other points is not the
same.

The moderaton's note is correct.
