What happens when you rotate an SVG
Rotating a photo means resampling every pixel. Rotating an SVG means writing one transform: the drawing is wrapped in a group that is turned around the canvas, and the canvas — the viewBox and the width and height — swaps its two sides when the turn is 90° or 270°. Not a single coordinate in your paths is rewritten.
That is also why the result is exact. There is no interpolation, no soft edges, no drift after four turns — a quarter turn four times gives you the original file back, byte for byte.
