Yes that's called the trigger. You have a trigger, that leads you to focus on and review what caused said trigger, and reach conclusions.

The ban is the trigger. The review is about to happen, so they really can't talk about its result yet. For all you and me know, said review will say their processes are just fine which I would personally disagree with but it could happen. Then, if there was an issue, they will update their processes, which is the end goal stated.

So your quote:

> the ban is the focus – not what led to the ban

The ban is the trigger that starts it, but the focus, the thing on which they will work, is their process. "Something important happened so we will spend lots of time figuring it out how it could have happened despite our processes made to protect against it" makes it pretty clear the focus, the thing they will spend their time on, is the review of their processes.
