That might be implementation-dependent or it might even come down to something as simple as the in which order the operating system returns files/directories when asked for a listing. In other words, unless you can find something in the documentation (or Python's import implementation) that confirms your preferred search order observation, I would not count on it working the same way with all systems, all Pythons, or even all directory names.
