And if we are using that logic, why does it keep going to Svartalfheim? Midgard is between Jotunheim and Nidavellir. But the vast majority of the portals go to Svartalfhiem.
That's backwards thinking. Thor is the protector of man, both in the comics and in the mythology. Of course he will always have some of his focus toward that realm. Jane is one thing the comics introduced to establish that connection.
Midgard isn't just between two realms. Look at the drawings in the movie.
