ok let me spell this out
<?php
//starting session
session_start();
//set session multidimensional array key equal to some value
$_SESSION['test']['test1']='XXXXXXXXXXXXXXXXXXXXXXX etc 50 lines';
//set $a variable equal to the value of $_SESSION['test']['test1']
$a=$_SESSION['test']['test1'];
//print the value of $a and get the right output XXXXXXX etc
print $a; //prints XXXXXXXXXXXXXX etc
//reset $_SESSION['test'] to an empty array
$_SESSION['test']=array();
//once again print the output of $a and get an empty string;
print $a; //prints empty string
It's acting as if I am setting $a to be a reference of
$_SESSION['test']['test1'], even though I am not.
I know php tries to optimize memory space by sharing the space with
multiple variable that have the same value. But when one variables
value is changed, It's supposed to copy the data into a new chunk of
memory. It doesn't appear to be doing this here.

Of course it's blank. You're passing non-existing value (empty) for
it.
I don't see any bug here apart from your script being buggy..

did you see the output of the XXXXXXXXXXXXXXXX or was it blank?
I think notices are turned of in my error reporting

Notice: Undefined index: test in /home/jani/t.php on line 69
