Subdirectories can belong to different repos. In modern IDEs like Intellij or Eclipse it's possible to work with multiple project roots in the same window (e.g. if you have a common library for microservices and want to redesign its API and make changes everywhere at once). The good thing here is that in most cases you work with just a fraction of your code and with a single project root, switching to multi-project view only in rare big reengineering tasks.
