All I have to say is that you have a pool table, set it up and try it a few times.
As with all of the diagrams, each really only represents the existence of the shot shown. They may not be perfect (and I know a little about perfectionism).
Believe me, I would not look to set up for it, as it is a very nonconventional play. After all, thin cutting the object ball with straight draw or extreme back-spin without curving or creating a whipping action is not easy for everyone. And that is where the danger lies. Or, if you are unlucky enough to hit between the balls vs hitting any ball solidly. But even then, the draw should help avoid the trap.
If you have never in 100,000's of different break plays tried this, then you only think it doesn't work.

The poster is meant more as a fun thing with a few irregular shots for breaking up the rack. There isn't any misinformation.
