There are 4 possibilities for this decrease. At the first red line, if it breaks there it would close the gap at the indicated place, if it breaks even further, it will descend even further to the small gap. If he breaks through that even further, he will make a Touchdown on the last red line where he will then go back to the upward direction.

The green line has now finally broken it. Now let's see if he also breaks the first red line. If it also goes through this, it will fill the first hole. And then we wait further.

The first hole has also been filled, now it will fill the small hole. The last target is the Red line, the touchdown line.
