is_front_page() returns true outside the loop – inside the loop it returns false

hello,

I am using on my index.php the following code:


var_dump(is_front_page());

if ( is_front_page() )
{
// check for referer and show two latest posts excerpts
//biq_check_referer();
query_posts(array( 'posts_per_page' => '2', 'category_name' => 'Blog Post' ));

echo ' <div id="latest_post_container">' . "\n";
echo ' <div id="latest_post">' . "\n";

if ( have_posts() )
{
while(have_posts())
{
the_post();
$biq_id = get_the_ID();
echo ' <div ';
post_class();
echo ' id="co-post-' . get_the_ID() . '">' . "\n";
$result = is_front_page();
var_dump($result);
echo 'index.php:' . is_front_page() . ':
' . "\n";
echo ' <h3>' . the_title( '', '', false) . '</h3>' . "\n";
// echo ' <h3>' . the_title( '', '', false) . '</h3>' . "\n";
// echo ' <h3>' . the_title( '', '', false) . '</h3>' . "\n";
// echo ' <h3>' . the_title( '', '', false) . '</h3>' . "\n";
the_excerpt();
echo ' </div>' . "\n";
}
}
wp_reset_query();

echo ' </div>' . "\n";
echo ' </div>' . "\n";
}

the is_front_page() function returns true outside the loop, but inside it is returning false.
