Same camera — not the same pixels
Each option is a separate render from the same camera. Archify checks the camera has not moved before every capture and spells the scheme out in the prompt, but the render service is an image model, so the massing can still drift between options: here the as-designed roof reads as one long plane while both schemes show a hip corner, the brick option grew a lawn, and the sand stucco scheme's bronze door didn't come through. Compare them as material directions, not as the drawing.
