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.
