I am a little confused by integration with iDev

I have CB, CB Subs and I'm integrating it with iDev

I have installed and confugired the CB Subs plug-in for iDev, which I understand allows me to assign iDev points to affiliates when users who they have brought to the site join and pay. If I can get that working, it sounds great, but I do have a big concern which someone who is familiar with both CB Subs and iDev might be able to shed light on.

Using the Joomla iDev plug-in (I know, nothing to do with you) is meant to allow new Joomla members to be automatically generated an iDev affiliate account. In the CB Subs manual, it says:
"If you do not have the iDevAffiliate system (for Joomla) installed on your website, then there is no need to proceed with the installation of this integration plugin."

I can only assume that when you say "iDevAffiliate system (for Joomla)" you mean an installation of the iDev script in a sub-folder and along with iDev's Joomla plug-in? (Correct me if 'iDevAffiliate system (for Joomla)' is something else )
The issue is that replicating membership between Joomla and iDev doesn't work when someone joins using the CB/CB Subs registration process.

This from an email from Jim Webster at iDev support:
That Joomla plugin does not support Community Builder for auto-account creation, it never has. It supports auto-account creation for the stock Joomla signup form and the Virtuemart signup form

What a ridiculous situation! I believe you are misleading users in your documentation. Surely using both the iDev Joomla plug-in and the CB Plug-in together is never going to work, because if you are using CB Subs you're not going to be using the joomla sign-up process.

What exactly is going on?
