As Chip stated, you're checking two different files here, 
$stylesheet_dir/style.css and $template_dir/css/style.css (note there's 
two differences, you should stick to the stylesheet directory for all of 

However, that's probably not your issue. The "bad one" that you don't 
want is hardcoded into header.php in the theme:

<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 
'stylesheet_url' ); ?>" />

The way I'd change it is to filter that instead.

add_filter('stylesheet_url', function () {
	return get_stylesheet_directory_uri() . '/css/style.css';
