Although they need to be the same layer.
Two identical layers are likely to be as big as two different ones, assuming the same colours.

in the resulting GIF you only have one layer per frame.
any decent gif animation package should optimize that no matter how things were arranged in the source files.
worst case scenario, assuming your gif writing software doesn't work like that: just run the gif through GIMP's "optimize for gif" or gifsicle or something like that.

in the gif,
when saved, all the stuff that remains the same per frame is discarded after the first frame that uses it.

Indeed,
but I find that images which are the same do not optimise as well as if you delete all the same bits from the subsequent layers and have a transparency through to the base layer.
I am not wording this well, bear with me.
