They’re saying it’s impossible to view objects at astronomical distances from different angles. If I were to move five feet to the left of a normally sized picture that is five feet away from me, I would have a vastly different view of the picture. If that same picture was the size of a skyscraper and, say, a mile away, my five foot shift to the left would functionally offer no different view of the picture.
Now multiply the distance and size of the skyscraper sized picture by billions and you’ll see that even looking at a nebula many thousands of light years away from vantage points thousands of miles apart would offer no difference in the angle at which we view the nebula.
But OP is mistaking angle for rotation. I can tilt my head in any of those instances and get the same effect for any object at any distance.
