Profile Isn't Being Selected for All of It's Attributes

Complicated one so I will try and explain.  I have a core customer schema which has the primary identity representing an individual.  Each customer can have multiple accounts so there is another identity field on that schema Account ID.  There are several other schemas with account information, all of these have the Account ID as the primary identity on the schema and all use the same Account ID Identity Namespace.  Based on my understanding the various data on those tables make up the profile fragments that I can then use to create an audience, however when I try and build a rule it is not selecting the profile for all of the available values.

Ex. Customer X has Customer ID ABC on core customer schema he also has AccountID's 123, 456 and 789 on the same schema.  Account Info Schema has Account ID as the primary identity for that schema and Customer X has 3 rows, one for each account.  This schema has a field "Account Type" and each account has a different account type 123 - Personal, 456 - Business, 789 - Savings. 

When I create an audience my expectation would be that the Profile associated with ABC would get selected whether I I have an account type of Personal, Business or Savings, however I'm only seeing it for 1.  Any help appreciated.
