I (not a designer) figure it's like the "rules" of photography such as the "rule of 3rds".
For those unfamiliar, the rule is that the main focal point (the bit you want to draw the observer into the picture first - such as the eye of a the person in a portrait) of the picture should be at the intersection of one third from the edges of the picture.
Another "rule" is the "sacred geometry" where elements that have long edges are more appealing when they are in alignment either with other "lines" in the image, or with the edges of the image itself. I've taken many landscape photos with a camera leveled with a gyroscope stabiliser (or just a spirit level when on a tripod) but the resulting images didn't "pop" until they were rotated so the ground aligned with the frame, or the picture skewed so the walls of buildings were truly vertical.
But then I've seen some incredible photographs that break those rules and only work because they deliberately broke the rules - some quickly found examples (and article affirming my diatribe above :)) from natgeo: https://www.nationalgeographic.com/photography/article/break...
