I would think the 2nd diagram, since it's the only one shown scoring.
I believe the Japanese text below the diagrams attempts to explain problems when playing the break, like what causes missing long/short or getting a kiss. It looks like they keep the hit the same (the red paths only differ in length) while using the indicated spin and/or speed to get the different paths. Personally, I don't agree with their indications.
Traditionally, the best way to play the break is to score on the 3rd ball either full in the face, or slightly on the long side so that it trickles into the corner area. Meanwhile, the red goes 3 rails to the same long rail (the exact position depends on the speed of the equipment). Jaspers seems to like to place the red more towards the middle than the long rail, so there's not even agreement among top players.
I think most room players hit the shot too hard and with too much spin. Too hard makes controlling the red difficult, and too much spin makes it easy to go too long unless you hit it harder to compensate (thus the usual combination).
It's such an easy shot that you definitely need to be aggressive and play softly for position. I play for slightly less than a 1/2-ball hit in order to pass the crossing point before the red to avoid the kiss off the 3rd rail. I use 1:30 english at most and modulate my speed to hit the long side of the 3rd ball. If I find that the red is traveling too far for the speed needed to score properly, then I'll start shooting more of a middle ball with the same spin to get back on the correct path. The only time I'll use more sidespin is on very short tables with old cloth.
Btw, I notice that the bottom diagram has the ball placed on the left starting position instead of the right. There's no difference - it's completely symmetrical and is only a matter of preference. That said, if you score on the top of the white and it ends up in the middle of the short rail, you might have to stretch to use it first for the following shot if you're right-handed and start from the right side. This is a minor point.
