If you zoom in on the coverage map, you notice that it's splines manually drawn by whoever made the map.
This isn't the output of some fancy RF model figuring out exactly where you'll get coverage. Nor is it circles of a specific diameter around ground stations. Or even hexagonal cells where coverage will be allowed/denied in their backend config.
In places it seems to follow countries territorial waters (which would be expected due to regulatory issues), but in others it spills out into international waters.
Overall, the map has sufficient 'oddities' that I think there is a good chance it's a rough hand made 'guestimate' coverage map, and won't perfectly reflect where coverage will really be delivered.
