Basically if you want all of your super moderators to have the same moderator permissions, make them a moderator and add them to the moderator user group where you have set up your permissions.
If for some reason you want some super moderators to have just certain permissions, then you could assign those permissions individually in your first screenshot. You would also use these individual permissions for any forum moderators that you create, as these permissions will then only apply to the forum that you are allocating them moderator status to (unlike the moderator group which gives the permissions across the whole forums).
That's what I gathered from playing around with permissions.
If you have a forum that has super moderators and sectional moderators, set everything you want super moderators to have in the user group permissions if you want them all to have the same permissions. Then for sectional moderators, don't give the user group any moderating permissions and instead set them in the node permissions. The same thing could be applied if you only have one moderator user group, but want each moderator to have different permissions.
