Unless there’s a footing these straps are being anchored to that I’m not seeing, I doubt it’ll do very much besides potentially acting as very dangerous whips.
I’ve seen these deck strap things that you push way down into the ground and as you pull them up a little the flatten out and turn sideways. Really easy to install and harder than hell to pull out. I think it’s called an earth anchor maybe. I bet that’s what he used here.

You’d be surprized how strong an industrial screwed-in ground anchor holds. And it has to be anchored at the correct angle towards the load.
So, most likely, they will not just rip out, and they have a good chance to add a significant force holding down that roof.
If done properly, of course.
If the roof doesn’t crack from the added pressure points.
There seems to be an extra bar/pole at the top to distribute the load, though.
