multisite sync with add on blog

I installed in both master site and add on blog
activated Both. tried to sync and it says all users synced and when I check nothing was synced.

maybe I'm miss thinking this here is my setup
main site has theses users and sites registered
on the Network Admin side of main site
with matching blogs

on the Site Admin side of the site
there is no users just the
Admin account

When the users register and create a Site shouldn't they be created as users with a log in to the main site if they log in from the main site with their username and password they used to create a Blog?

What I wanted to do is create a membership site for only users on the help site
for Pro Members and offer some but not all to non Pro Members first thing I needed was same login and this plugin WordPress User Synchronization I thought was perfect for it.

Am I wrong for thinking that
Please Let me know

After reading some more threads it seams I can't do what I need to do to Sync add on blogs on the same Multisite network with the main site.
Anyone know how I can proceed?

Is there any plans to make this Multisite compatible. would be nice. If someone has 5 or 10 blogs and they want one login for their users on a multisite setup.
