JPEG is a lossy compression scheme. the reason it gets its high compression factors is that it throws away stuff. it was designed specifically for photographic use (Joint Photographic Experts Group = JPEG).

In which case, there is no sensible logic to it. If you tell the programme to save the file at the biggest possible size, the logical thing, to me, would be for it to save everything. If it proceeds to chuck away information after getting that instruction, it is not a clever file format for photographic use.
