I mean in generalnot in this case specifically
combined frames can be useful if you have modifications in consecutive frames in different parts of the image, say:
if you're not using '.' as a transparent color frame to can be optimized as
where o is transparent.
but if . is the transparent colour you need to store the whole of frame 2, and that's less efficient since a 3 1-colour blocks can be compressed a lot better than a whole frame.
