What's most interesting here is the detailed info on bacterial contamination and treatment of bite wounds, the medical protocol specific for grizzly attacks. The victim and others interviewed are matter of fact about risks inherent in that area.I would guess the 'attack' would be similar for any bear, just more violent with some, but the area in the article has specific procedures in place for the aftermath.
Also note that the hunter startled the bear; I've read that hikers will attach bells to their packs to make noise to warn bears away. Maybe a seasonal thing? Bears wake from hibernation hungry: might the pack bells sound like lunch bell?!
