I felt the same way, the question is pretty ambiguous, there are two readings, one corresponds with a somewhat "unintuitive" answer provided, and another doesn't, but is maybe more intuitive to some people, and yet "everyone got it wrong". I think its a bad question because the terms aren't defined clearly, but the "everyone got it wrong besides these people" framing is also not really true imo. I also didn't see why the original answer isn't considered defensible because from the view inside the circle, each of the 4 "rotations" doesn't look like a rotation because you don't start and end them from the same view.
