Sure, I'm just saying it makes an executable file upload more likely. Because if a file like settings.php is executable by Apache, it implies that (at least in this directory) any .php file is executable by Apache, rather than a single whitelisted index.php or some wsgi setup. So maybe the same configuration applies to a user upload directory. If you find a way to upload a .php file to a web directory on the same server, there is a possibility you can execute it - with higher success probability than if you did not know about settings.php being executable.
