Retrieve number of post from multiple categories.

I found a solution that will post my category title+posts randomly and by the number i set, my the problem is i cant list it by twos with the category title because they act like separate set of queries, i cant put the two result in one

coz the second post result creates that another

like a separate query the title only comes with the first post, so i cant combine the cat title and the two posts from the query. Is there a css fix for this to make it like?

<h1>title1</h1> | <h1>title2</h1> | <h1>title3</h1>
<>post1</> | <>post3</> | <>post5</>
<>post2</> | <>post4</> | <>post6</>

function get_posts_for_cat_ordered( $cats = array(), $posts_per_cat = 2 ) {
  if ( empty($cats) ) return false;
  $args = array('posts_per_page' => 99, 'category__in' => $cats, 'orderby' => 'rand');
  $q = new WP_Query( $args );
  $posts_ordered = array();
  $done = 0;
  while ( $q->have_posts() ) : $q->the_post();
    global $post;
    $cats = get_the_category();
    $cat = array_shift( $cats );
    if ( ! isset($posts_ordered[$cat->slug]) )
      $posts_ordered[$cat->slug] = array('term' => $cat);
    if ( ! isset($posts_ordered[$cat->slug]['posts']) )
      $posts_ordered[$cat->slug]['posts'] = array();
    if ( count($posts_ordered[$cat->slug]['posts']) == $posts_per_cat ) {
       $done++;
       if ( $done == count($cats) ) return $posts_ordered;
       continue;
    }
    $posts_ordered[$cat->slug]['posts'][] = $post;
  endwhile;
  wp_reset_postdata();
  return $posts_ordered;
}

$cats = array(12, 13, 14);
$posts_per_category = 2;
$posts_ordered = get_posts_for_cat_ordered( $cats, $posts_per_category );

if ( ! empty($posts_ordered) ) { foreach ( $posts_ordered as $loop_data) {

  // Example category heading
  echo '<h2><a href="' . get_term_link($loop_data['term'], 'category') . '">' . $loop_data['term']->name . '</a></h2>';
  global $post;
  foreach ( $loop_data['posts'] as $post) {
    setup_postdata($post);
?>

  <!-- Example post content -->
  <?php the_title(); ?><br />
  <?php the_content(); ?><br />

<?php
  }
  wp_reset_postdata();

} }

Also it doesnt work on posts with two categories or more..
