dtralex on "Showing Related Posts at Two Places"

Hello, I am using this code

<?php $orig_post = $post;
global $post;
$categories = get_the_category($post->ID);
if ($categories) {
$category_ids = array();
foreach($categories as $individual_category) $category_ids[] = $individual_category->term_id;
$args=array(
'category__in' => $category_ids,
'post__not_in' => array($post->ID),
'posts_per_page'=> 5, // Number of related posts that will be shown.
'caller_get_posts'=>1
);
$my_query = new wp_query( $args );
if( $my_query->have_posts() ) {
echo '<div id="related_posts"><h3>Related Posts</h3>

';
while( $my_query->have_posts() ) {
$my_query->the_post();?>

<div class="relatedthumb">
<ul style="list-style-type:disc">

• "><?php the_title(); ?>

</div>

<?
}
echo '</div>';
}
}
$post = $orig_post;
wp_reset_query(); ?>

to show related posts in single.php

this way I am able to show the related posts below the post.

I want to show the second related post in sidebar.

I am able to show the related post in sidebar but it is showing the same related posts as it was shown below the post.

Can it be possible to show different related post? Like 1-5 related posts below the posts and 6-10 related posts in the sidebar...
