Hello @vodnalar26 

HR has arranged lunch in the office cafeteria and have informed the security guard at the gate to allow only those who have:
1. Company's ID card/badge.
2. Allowed members list with names of specific employees.

So, security guard is going to use "Deny Unless" as both of the above conditions as AND has to be true.

Let's say the security guard is in a good mood and doesn't care about validating the list, then security guard is going to use "Allow If" as one of the condition has to be true. You have a company badge, well be my guest and go on to enjoy your meal.

So, the "Deny Unless" in your scenario is not working because all the ACLs on the target table has to be true. 

I would recommend to go with "Allow If" to meet your requirement here and in parallel learn all the "Deny Unless" so that you can make decision which ACL to go with in near future for any such new requirements.
