Clarification around about page hidden groups and overlapping visible groups

Why bother putting the same group to be hidden AND to be shown on purpose? IIRC the former setting hides the ‘Our Admins’ / ‘Our Moderators’ section, while the latter adds more groups below. From my testing, it does not look at the first setting to control the visibility. So if you add Moderators to both, a new section titled ‘moderators’ will be shown with members, while the ‘Our Moderators’ section will be removed.
