blog templates plugin doesn't copy images

New blog templates actualt doesn't copy media files in wp 3.5. I took a look at plugin code an noticed something strange.

As i could see wp 3.5 mu doesn't use blogs.dir folder anymore however in plugin file (blogtemplatesfiles/blog_templates.php) i found lines below:

after line 700:

$dir_to_copy = ABSPATH . 'wp-content/blogs.dir/' . $template['blog_id'] . '/files';
$dir_to_copy = apply_filters('blog_templates-copy-source_directory', $dir_to_copy, $template, $blog_id, $user_id);

$dir_to_copy_into = ABSPATH .'wp-content/blogs.dir/' . $blog_id . '/files';
$dir_to_copy_into = apply_filters('blog_templates-copy-target_directory', $dir_to_copy_into, $template, $blog_id, $user_id);

In wp 3.5 mu i noticed file structure is:

wp-content/uploads/sites/$blog_ID

Is plugin outdated or am i wrong?
any help will be much appreciated.
