I opened Apple Maps in globe mode and I still have trouble visualizing the water path.
Does it help to point out that the water path looks suspiciously like the day/night line on a map?

yes!! why is that ? :)
The day/light line is a great circle. The "straight line paths" are great-circle segments.
It's going South and then trying to close the loop from behind. It gets interrupted by land before the loop closes.
Hope it makes sense.
