This should be the case:

add_action( 'pre_get_posts', 'wpdit_pre_get_posts' );function wpdit_pre_get_posts( $wp_query ) {    if ( is_home() || is_front_page() ){        $wp_query->set( 'category__in', array(1) );    }    return $wp_query;}

Your requirement is "the first page only displays the article of the specified category", so we should only get the articles under the specified category in the first page;
Instead of presenting all the articles to determine which one to display or not to display on the homepage.
