But if I turn around it does the same the other way - obviously the earth is not a cube shape with bulging sides - but what is the explanation for this phenomenon?

Yes, its because the earth is round and if you look out an airplane window or off a mountain, you can see the "bend". It's because that is where your eyes see it's curve. Hope I didn't confuse you more
