Looks like they have at least two layers of shingles there. I've never liked the idea of putting new shingles over old. I know it's cheaper but it just seems like shoddy workmanship to me. Also, you don't really know what condition the roof deck is in if you do it that way.
Be careful when following the masses. Sometimes the M is silent.

I think I would fire a contractor that did that to my roof. They could easily crack a truss and I wouldn't know. Plus, that machine would tear up the yard with its tires.

The work saved versus the risk is a ratio I'd rather avoid. I have always just pushed the old shingles to the ground, and then gathered them up and thrown them in the trash bin. Far less than a half a day's work.
Looks like an industrial area and parking lot below. My guess, it's a contractor's own office building, so they are just screwing around and doing it that way 'cause why not?
No, I don't see this ever being done residentially, the yard repairs would outweigh any labor savings (if there are any) even if done perfect.
