I guess I'm supposed to explain.
If Hinson leads off the first they can put three runners on and make three outs before running out of bases.
The seven hitter will lead off the second. Meaning Hinson will bat fourth. If two batters make outs and one is on base when Hinson steps to the plate, that runner could then be caught stealing for the third out. Since Hinson was still batting at the end of the second he would also lead off the third and the whole cycle would start over.
