This is really about inference, and less about "decision-making."

First, the bar is has a action-response rule-based mechanism based on the input of winning or losing combined with which direction it came from right or left. That's it.

An externality can then infer that the bar has made a decision, but of course, the bar has made no such decision.

This is still useful, but it's overblown to call this "decision-making" outside of decisions made exclusively within a strict framework of primitive rules. That said, many fundamental human reactions and decisions follow a pretty strict framework of primitive rules. That's why most people fail to grok the ladder of inference: https://www.youtube.com/watch?v=KJLqOclPqis
