Using get_option() ? Why?

I'm noticing in a theme that I'm working on for someone they use:

<?php echo get_the_title(get_option('page_for_posts')); ?>

What is the advantage or idea behind this? Is this not just <?php the_title(); ?>?

I realize get_option() can be used to get fields from the wp_options table but I'm not sure why, as it seems like this can all be done another way. Any insight?
