get_post code at static page content

Hello
I am trying to display post content at static page.
At first i will describe what i have.
So i have 2 posts called Post 1 and Post 2 and i have static page called Page 1
Now what i’ve done.
So i have installed exec-php in order to use php code at static page. Then i put code listed below to page 1

<?php
$lastposts = get_posts('numberposts=3&category=3');
foreach($lastposts as $post) :
    setup_postdata($post);
    ?>
       <a href="<?php the_permalink(); ?>"
id="post-<?php the_ID(); ?>"><?php the_title(); ?></a>
    <?php the_content(); ?>
<?php endforeach; ?>

And after all i see at my “page 1” something like that:

link to Page 1
content from post 2
Link to page 1
content from post 1

when i am putting same code to page template everything is ok it means that i see at screen this:

Link do Post 2
content from post 2
Link to Post 1
content from post 1

So why if i put code to static page
<?php the_permalink(); ?> will give me wrong linking ?
