My amateur's view: that wall has been engineered to take a significant load, much more than a typical side-wall. One tip-off for me is the horizontal blocking, I don't think that's fire-blocking, it's too high up. When you load up a stud, there are two failure modes: either it buckles, or the end grain gets crushed. Unless a stud is short it will buckle before it gets crushed. The horizontal blocking shortens the effective length of the stud so it can carry a heavier load.
You can't see the width of the building, but it looks like a significant span, which would create significant side-wall loads, particularly in a place with high snow or wind loads. What's weird is that it looks like residential construction using pole barn techniques, where all the weight of the roof is on trusses and the trusses rest on poles. If there were some connector that we're not seeing that transferred the weight of the roof onto the entire wall and the roof were really wide then the wall would make sense.
Where did you see this? It looks interesting.
