The only way that I forsee this being expected behavior is if
$_POST['value_a'] == $_POST['value_b']

Usually when I am assigning an array to a session key, I will use:

$_SESSION['key'] = array('a'=>$a, 'b'=>$b);

I have never had any problems using either method, and tested that on my
two 5.1.1 installs which worked fine.
