How to make Super Admin automatically a user for each new blog.

When a new blog is created on my multi-site the Super Admin is not automatically a user of that site. Is this the way multi-site usually functions or have I altered it by adding code to make the new user a default to a different role than usual. I am using New Blog Template but not copying over the users. If I have the Super Admin users on the template site and copy the users over in a new blog then the new user also ends up with Admin rights.

I'm thinking maybe I could change this code.
function ds_new_user_meta($blog_id, $user_id) {
add_user_to_blog($blog_id, $user_id, 'shopowner' );
add_action( 'wpmu_new_blog', 'ds_new_user_meta', 10, 3 );
so that it also adds the multi-site super-admin users as users to the new blog?
