Yes. You are missing the point.
This is exactly the same; you don't need $_SESSION's in this case because all you're doing is POST'ing the data every time..
And that's what you are missing -- it's not continued POSTing!
Follow closely,
http://www.webbytedd.com/bb/php-run-php/
While I'm using a Submit Post button to go from this script to the next script I am NOT sending any data via the POST. To prove it, use FF and see what's passed.
All data is passed/available to the next script because the next script is an include.
For example, this parent script has the variable:
$test = "This is a test";
And the next script (either a.php, or b.php, or c.php -- your choice) simply echo's $test.
Please note, the contents of the variable $test was NOT passed via a POST, but rather retained because the parent script included the next script.
Do you see the difference?
Here's another example presenting the same technique in a different way:
http://www.webbytedd.com/bb/tedd/index.php
All the variables remain intact AND there is nothing in the REQUEST, SESSION nor COOKIE arrays.
I have a hard time trying to get people to understand this simple concept. It's so simple that people often overlook how powerful it is.
For example, with a little forethought, I think there isn't a script I've written that I could not have used this technique and dispensed with SESSION's all together. That's pretty powerful, don't you think?
Do you understand what I'm doing now?
no ill-intention meant.
That's Okay -- I realize you meant no ill-intent.
Neither do I -- I realize that occasionally simple concepts are hard for you smarter guys to get because you have to dumb down a lot to consider what we're talking about. But I think it's an interesting concept to consider.

at it's simplest is this correct..?

index.php
<?php
$variables = $_POST;
include 'anotherscript.php';
?>

anotherscript.php
<?php
print_r( $variables ); //include has access to $variables from parent
print_r( $_POST ); //include has access to post data as well
?>

I'm struggling to follow here I thinks! lol

I don't think you're missing the point Nathan, I think you've hit it on the head. This technique does not solve the problem of passing variables between requests. I think the only benefit here is to avoid having to repost data by including the next script rather than bouncing off the browser.

Or maybe I'm missing the point.
