The grizzlies were far more likely to attack but due to distance and spotting them early to avoid there was no issue.

They are not more likely to attack, you just perceive them that way. As long as you don't do something that makes them feel threatened you are statistically in far more danger around the humans you cross paths with. I don't remember where I read it, but even with the tiny amount of bear attack, even those attacks are most often the result of human fear causing humans to be aggressive and then lose the fight they started. For instance a hunter with a gun may get scared, shoot the grizzly, and then hit it without a fatal shot. They just created a danger that wasn't there. "Fear is the mind killer".
