Do WP 3.7 plugin autoupdates work with WPMU DEV plugins?

WP 3.7 offers a filter to be dropped into wp-config.php that will automatically keep plugins and theme updated.

add_filter( 'auto_update_plugin', '__return_true' );
add_filter( 'auto_update_theme', '__return_true' );

Are WPMU DEV plugins supported by this feature, or does it only work with repository-based plugins?
