Limiting indexed content types in v 1.3

In version 1.2 it seemed the plugin only indexed pages and posts by default and I could add custom content types to index with, for instance:

add_filter('lift_indexed_post_types', function( $post_types ){
    $post_types[] = 'audio';
    $post_types[] = 'video';
}

In version 1.3 the plugin indexes every content type by default.

I had to do this to limit to just the content types I wanted indexed:

add_filter('lift_indexed_post_types', function( $post_types ){
    unset($post_types);
    $post_types[] = 'audio';
    $post_types[] = 'video';
    $post_types[] = 'post';
    $post_types[] = 'page';
    return $post_types;
});

It seems to work, is this correct?
