I don't have Facebook, so cannot join the group and watch the video (I did try to watch it).
Is he specifically discussing day packs with no hip belt? If he is, why don't all Kifaru day packs have departure angle adjustment straps (because without a frame and hip belt they cannot 'lift' the load off the shoulders and thus are not load lifters)?
I copied this directly from a post Mel made.
"This post is about lifter straps! Lots of guys without much pack experience think the term lifter straps means that when you pull the straps it is supposed to “lift” the pack/load on your back! I guess lifter straps is kind of a misnomer term

! When you have a full suspension pack with waistbelt, once you tighten the waistbelt, then you would pull on the lifter straps. If the top of the stays in the pack are above your shoulder, then you will get true shoulder lift! That means the shoulder straps will be slightly lifted from the shoulders, leaving the weight of the pack fully supported on your hips, with no weight on the shoulders. If the top of the stays are not above your shoulder, then when you pull the lifter straps, it will just snug the top of the pack into your upper back, and keeping the top of the pack from falling away from your back

! Now, if you have a shoulder load only pack with lifter straps, then once you set the preferred tension on the shoulder straps, you would pull on the lifter straps to snug the top of the pack into your upper back, but not get any shoulder lift, as you have no waistbelt to transfer the load to...hope this makes sense

! I won’t get into how you are able to adjust the tension of the shoulder straps and lifter straps to control how the load is carried, especially with a waistbelt

! Below in the pics you can see on the Coyote Xing Pack how the lifter straps are doing their job by lifting the shoulder straps slightly, and transferring the weight to the waistbelt! I was able to do this because as you can see, the top of the stays are above my shoulders. On the Wolf Gray 360° Pack without waistbelt, the lifter straps snug the top of the pack into my upper back, keeping the pack one with me for maximum comfort

! Hope this explanation of lifter straps helps you guys that don’t have a lot of pack experience yet
