Right, a part of the film's design was "It should curve enough to look cool".
At first I found myself questioning the speed of the rotation, it seemed faster than claimed - 1rpm is not a lot?
Then I did the math: A quarter turn is a right angle, floor becomes wall. A quarter minute is every 15 seconds. That's about what's happening in the video. And it's quite disconcerting to watch continuously. I would not want to see faster rotation.
So the video is chosen for speed of motion and size of ring, and how they look. 1 G would either be faster motion or less curve, and it seems that the author didn't want those, for valid aesthetic reasons.
