I don't understand what this means. Can anyone explain it?

This means that the amount of time it takes the Sun to trace that circle is the same amount of time as Uranus' orbital period.

It's far from exact. Because none of the heavy planets are in resonance with each other, they will never align the same way twice. So the pattern has some chaos in it. If I let the simulation run longer before taking a screen shot, rather than overlapping spirographs, The image would just get busier and busier until all you saw was one big yellow blob in the middle of the screen.
