It means you attached the detail view boundary/callout to geometry on your original view
Which means if the detail boundary changes, dimensions or anything like that the actual detail view will update properly.. Its not needed in all cases but you could run into a situation like this..
As you can see the height of the keyway was changed and the detail is not correct anymore since the boundry didn't move with the change/modification.
