Interesting. The very, very few I've seen do this will start with reverse shrugs and when the rep get harder, continue with the reverse Hi-pulls/Upright's. Or Vice Versa in some cases. Good combo pump, I would think.
Though needing a full ROM still remains a myth today in BB'ing. The bigger, stronger men seem to favor partial reps in all their workouts...and with ultimate success. But than again, if full ROM's work for you...than go for it. In the video that guy is raising the bar as high as he can, so that could be considered a full ROM for him.
Good Luck.
