Depending on the author's dev practices, the script might have been in a volume so that editing it on the host would allow the container to receive the changes as they get saved. While I wouldn't normally suggest this approach, it can be handy at times.

Yup that was exactly the problem: I had the code in a folder that was mounted to the container as a volume.

Mounting host directory in a container is quite the popular approach. n almost every development tutorials I have read using Docker mentions this approach.
