How do I change the number of posts indicators

Hello. I use this hack

add_filter( 'parse_query', 'my_pagetemplate_filter' );
function my_pagetemplate_filter( $query ) {
	if(!current_user_can('edit_others_posts')){
		global $current_user;
		set_query_var( 'author',$current_user->id );
	}
}

It displays only their authors write, but figures remain the same number of posts. Screenshot
