Please refer to the below articlehttps://www.augforums.com/forums/everything-else/restriction-groups/

The difference between A and B comes into play if any Customer Accounts were to appear in multiple groups. If that was the case:

- For Type B groups, users can only see the account if they are placed in ALL of the restriction groups in which that account appears.

- For Type A groups, users only have to be a member of ONE of the restriction groups with the account in question to have access to that account.

Your particular solution would work with Type A or Type B since none of your customer accounts are in multiple restriction groups.
