As far as I remember this was not a strict causation with no way back and no exceptions. They just delisted everything to get breathing air and would sort it out later. The post you linked has this:
We are still in ongoing discussions with payment processors and will be re-introducing paid content slowly to ensure we can confidently support the widest range of creators in the long term.
So one guess, for some of the games would be, that they might be such slowly re-introduced games. Maybe some tests or special circumstances.
Does not matter. The point is, that this was and is not a 100% thing.
