[Plugin: Infinite-Scroll] Infinite Scroll and custom loops

Trying to get infinite scroll to work with a custom loop.

My loop up top on the homepage looks like this:

<?php
					$counter = 1;
					query_posts( array(
						'showposts' => get_option('freshlife_featured_post_num'),
						'tag' => get_option('freshlife_featured_post_tags')
					) );
					if( have_posts() ) : while( have_posts() ) : the_post();
				?>

// do stuff

<?php $counter++; endwhile; endif; wp_reset_query(); query_posts('offset=4'); ?>

That outputs the first 4 posts. Then, the rest of the content (starting with post 5) is outputted using this:

<?php if (have_posts()) : while ( have_posts() ) : the_post() ?>
		<?php include(TEMPLATEPATH. '/includes/templates/loop.php'); ?>
	<?php endwhile; ?>
<div class="clear"></div>
	<?php if (function_exists('wp_pagenavi')) wp_pagenavi(); else { ?>
		<div class="pagination">
	    	<div class="left"><?php previous_posts_link(__('Newer Entries', 'themejunkie')) ?></div>
	   		<div class="right"><?php next_posts_link(__('Older Entries', 'themejunkie')) ?></div>
	    	<div class="clear"></div>
		</div> <!-- end .pagination -->
	<?php } ?>
	<?php else : ?>
	<?php endif; ?>

The problem is, after I scroll down the blog towards the end of my list of posts and the infinite scroll kicks in, it loads post number 5 again instead of loading post number 15 or whatever it is at the end.

What’s going on here? Any way to get this to work?
