If the three balls, which swing around the same pivot point, are set in motion, they swing at different speeds. While the ball weight with the longest pendulum arm swings once, the middle one swings twice and the top one swings three times.

Similar to the way that the sound of three different bells always leads to the simultaneous ringing of all three, the three pendulums swinging at different speeds end up in the same line at the same time, as well.
