In the top picture your S11/S12 is an array, which gets auto-indexed in the for loop (the little square thing at the border) which essentially iterates over the elements which allows you to read the items individually.

In the bottom picture your S12/S12 is part of a cluster (think struct in other languages). You cannot iterate over this like you do in the for loop.
