Why do we have if(have_posts()) and while ($the_query->have_posts()) ?

Both if and while are conditional statement. why do we have both of them here? <?php if(have_posts()): while ($the_query->have_posts()): $the_query -> the_post(); ?>

if(have_posts()) means if there are posts while ($the_query->have_posts()) means while there are posts in the query, do something

Can't we just use

<?php if($the_query->have_posts()): $the_query -> the_post(); ?>

Yeah, I tried it. it only displayed one post. OK, I see, while is a loop.
