I think the comment points to the fact that for images that are natural targets for the JPEG compression method, tiled TIFF files may be better suited. Take your average photograph: A rectangle (tile) of pixels in the middle of the sky, the sea, the grass, a wall, etc. contains a lot of redundancy, given that all the pixels are of very similar color. A strip, covering the scene from the left end to the right one, will be less uniform.
