Can we test a measure's value in our RLS?

I was trying to simplify the example, but let me describe the full issue with screenshots.

I have the table Practice data, and I'm testing to see if Report_access is True (which should determine if anything can be seen or if the whole report is empty) and then also filtering the data that the user can see by location and by organization. The visual I'm viewing only has data from the Practice data table.

The Security table RLS is: [user email]  = Userprincipalname()

Report access is defined:

Report_access = contains ('Security', [Report name],[This_report])

This_report is set to the name of this report.

So the first part of the RLS test on the data table is testing to see if this user even has access to this report.

Here are the values in my two tables.

These next slides are what I captured and documented back in March. Depending upon the report name, the entries in the Report Data would change appropriately. But today, I've opened the same PBIX file that I saved back in March. And no matter what I set the report name value, the data table report displays all of the entries. And even if I use View as Roles and use an imaginary userid that isn't in the security table, I'm still able to see all of the entries in the data table. It's as if the RLS filter isn't there.

Does the explanation make sense? IIf necessary, it's a small practice file that I ran the original tests on, and I could zip it if we have a way to share files.
