success event, referrer and document.referrer

Dear experts,

I got a question about document.referrer and adobe default Referrer.

Considering following visit, we've set document.referrer as following scenario, subdomain1 and subdomain2 are configured in internal URL filter

The question is, althought I can see document.referrer is set to subdomain1.domain.com on page B, while internal URL filter is configured,

1. what the Adobe Default Referrer value will be on Page B,

2. For event1, will it credit to www.google.com  OR subdomain1.domain.com OR None if I break down by Adobe default referrer?

Thank you.

H
