The loop always loops even if condition is not met

Not sure if the title describes my problem.

I’m trying to make a custom frontpage for my site. The frontpage includes a slideshow while the rest of the site doesn’t.

Fot this i work with a conditional statement:

?php if(is_home()) { ?>

	<div id="welcome">
		<h1>...</h1>
		slideshow
	</div>
	<div id="clear"></div>
<?php } else {?>
         <div id="content">
             <?php get_template_part( 'loop', 'index' );?>
             <?php get_sidebar(); ?>
         </div>
<?php } ?>

When i’m on the frontpage everything works fine. When i click a link the loop does the job. But the styling doesn’t work. When i use firebug to view the code the content div isn’t used so no styling is applied.

When i delete the else statement, the result is the same. So with

<?php get_template_part( 'loop', 'index' );?>
<?php get_sidebar(); ?>

removed, the loop still works. Why is this? I always thought get_template_part called the loop
