The geographical timing is there based on the timing of the theatrical release to get the greatest profit from the film. The movie ideally has a cinema run, then when ticket sales slow they release for purchase on physical media (or premium services), then after those sales slow they release for digital renting. They don't want the movie available on Netflix in a country where the theatrical release has not yet happened, or it's still in it's first run. Some of it is left-over from when films were in physical form and loaned out to theaters. There are only so many copies made. Now that modern theaters receive the movies as a download, that's not really a justification however there's still the publicity tours that accompany the release. They want a proper premier with the cast in each country. There's also language translations and such which would normally be done after the movie was already released. Basically there's various things they want to do which are difficult or impossible to do on a global scale, so they focus on one part of the world at a time. When your country is low on the list, it means the movie doesn't make it to your country for 6-12 months.
