Yes. The secondary as a whole is playing field and boundary.
That's not really how any of this works. You match formations and routes. In a standard Sky/Cloud setting, the boundary tends to get more help because the field has more space that the offense likes to attack. (Therefore the field safety is occupied with a route more often and isn't able to provide as much help.)
Against ISU, we were not often playing this version of quarters. We were frequently playing versions where matching happens between the safeties, and the corners were not expecting any help at all. For the same reason of offenses like to attack space, this tends to move the safeties toward the field. Without listening to him, I can only guess that this is what Babers was talking about. Watts is not getting as much help, but really neither is Jamison. You are sacrificing help outside to get more aggressive over the middle.
