It’s not just the order but the placement, the titling, and ultimately the whole message being presented. Windows managed to do this as backwardly as possible (no pun intended). Switching their button order vs. the Mac might not have mattered if Windows put the first button in the bottom left corner for predictability. Instead, they right-justified an entire group of left-ordered buttons so you have no way of knowing if the corner button will be the main action. Then they tended to use nondescript button titles, made worse by APIs that make it easier to pop up yes/no questions than Action1/Action2 (i.e. custom titles) so apps lazily trend toward nondescript. And then the OS had relatively tiny fonts without formatting that made it hard to understand at a glance what a message is even asking, requiring careful reading to proceed. A good UI is not a very simple thing, there are lots of details to be considered.
