Here’s my reading of it: when speaking about dynamical systems with several interdependent moving parts, humans are fond of asking “why” questions and looking for simple narratives in such systems where satisfying answers may not exist.

For example, imagine a three-body planetary system which exists in a pseudo-stable configuration for millions of years, until suddenly one of the planets gets slung off on a wild orbit and ejected from the system. A layman might be inclined to ask, “whoa, that’s weird, why did that happen?!” while the physicist will reply “All I can say is that planet A is where it is because of planets B & C, and B & C are where they are because of A.”
