Because it is inherent in the technology. Lower stages of a multi stage rocket separate and fall off as they run out of fuel. Where they fall is the question of where the launch site is and in which direction the rocket is launched.

A derailing is not the right analogy. That is an anomaly. Something which is not supposed to happen, and people are acting to prevent it. If you want a rail analogy this is like a train crossing a bridge between station A and B. It will keep happening because it is designed to happen. It is inherent in the design.
