When the touch sensor activates, the person with the sword goes to the right at a very fast pace, and then comes back at the same speed. When the falling person touches the sword person, it will go up. So, when you spam, the sword person will continue to do the things it is supposed to do, and when the falling person touches the ground, it touches the sword person too, if you get the timing when spamming. So it does both of the things (Go up in the air, and freezing in place).
