dgkhan,
I am a structural hard head and what the truss guys do most days of the week make me wonder, so my comments are based on structures not truss manufacturers logic.
If i was to look at the page as you have posted i would call the top N, right E, bottom W and left W. looking at the NW area, you need to take into consideration that the truss cords are not in a good orientation for the battens to attach or the wall to attach. I would be tempted to put in another hip girder and a few more jacks. maybe move the girder from the far w to closer to the center.
Arguing with an engineer is like wrestling with a pig in mud. After a while you realize that them like it
