Update: [2018-06-27] I found this post that confirms my question below ... the score card only counts clicking "Review" from within the "Microsoft Secure Score" UI itself and does not actually do any real telemetry to verify the reports are utilized. It is just counting clicks... (sigh) ...
It appears that the Microsoft Secure Score is only counting “last time you reviewed this report” based on clicking the Microsoft Secure Score link to the report rather than actually reviewing the report.
Can anyone confirm or invalidate this perception? [2018-06-27 - Confirmed - no real telemetry]
This report and others mentioned in the Microsoft Secure Score were reviewed on Thursday, June 21, 2018 in this tenant.
The "Microsoft Secure Score" says “6/14/2018” as last time the report was reviewed. This was the last time the reports were reached from clicking the links in the "Microsoft Secure Score" [Learn More] button, but not the last time the reports themselves were reviewed.

You should review user role group changes at least every week. There are several ways you can do this, including simply reviewing the list of users in different administrative role groups in the Office 365 Admin Portal, or by reviewing role administration activity in the last week from the Audit Log Search. You should do this because you should watch for illicit role group changes, which could give an attacker elevated privileges to perform more dangerous and impactful things in your tenancy.
