I think they don't wake up in the morning and say to themselves, I wonder how many humans I can kill today. They're more intent on eating I guess, and reproduction. The Eastern Brown will not attack, it's a more defensive stance really, but they will aggressively defend and that means a bite, which kills most often than not.
They have a fairly good tolerance as you may have seen in the video. They are happy to posture and give some warning. That's when it's prudent to stay still, back away very slowly. The snake is most likely to do the same.
