It allows black to live with four points and no problems.

If white fights the ko and wins, he gains over twenty points.

If white fights the ko and loses, he just loses the four points he gave up anyway. Black isn't going to take the time to play A and then B, when he is alive after A. B just isn't big enough yet.

So the ko isn't free, but it is very favorable for white.]
