The beauty of procedural animation is not thas it's realistic, but that very simple principles allow for good-enough results. It's something used for videogames or presentations, not simulations.

TL;DR: animation by simplistic algorithms is a beautiful technique, but a lousy simulator.

Making a more realistic "looking" simulation would not be more work or less simple.

For both, simply following the path of the first circle is both a simpler algorithm and closer to natural movement
