1) A big part of my point is that it doesn't matter what an author is thinking when it comes to discussing how others will react to it. I won't restate here my arguments on that topic.
2) We can safely say that the creator was thinking of brogramming. Aside from the fact it would be an astonishing coincidence, the original page uses as one of its examples "curl --header "X-GirlsAreBrosToo: 1" www.bropages.org". Calling this "bro" was not some sort of innocent accident.
