Original Note:
The missing context is that while you would not turn right or left, the reason this works is Great Circle Navigation. When the globe is projected into a flat map the shortest route between two points looks curved. If you used a string and a globe you'd see how it works. https://en.wikipedia.org/wiki/Great-circle_navigation
