I don't recall seeing this on BlackHawks. I worked at Sikorsky for a year as an intern, and all of the blades were zero twist. They did have a sweep at the tip, but no twist.
Those must have been factory rejects. As a CW3 UH-60 pilot that squeaked through Maintenance Test Pilot school I can assure you those blades are twisted sisters. I'm not Chuck Yeager and I haven't slept in a Holiday Inn Express lately however, I do know a thing or two about the Blackhawk.

Wile full scale do have some twist to the blades, not 10 degrees worth. A few degrees yes.
The Army's TH-67 (basically a Bell 206, yes?) has -10 degrees twist from root to tip. Blackhawk has over -13 degrees twist from root to tip.
