To understand all this you have to look at the history, going back several
decades.
For most of ham radio history, US hams were the most numerous. Except for the
Japanese 4th class licenses, the number of US hams is about equal to the rest
of the world combined. And because of American affluence and
industrialization, high power 'phone ham stations are/were most numerous in the USA.
For this and other reasons, it was decided long ago that the US 'phone bands
would be kept narrower than those allocated to DX, so the DX 'phones would
have someplace to work each other without having to deal with US QRM. For
example, when I was a Novice in 1967, the US 'phone/image subband was 3800-4000, and
the Canadian phone/image subband was 3725-4000. The Novice subband back then
was 3700-3750, and so we sometimes had VE 'phone QRM in the top half. In
practice, 3750-3800 was full of non-US 'phone operation. Working "split" is nothing
new; "phone DXers were doing it 50+ years ago.
As the number of US hams has grown, the 'phone/image subbands have been
widened, and the non-US hams have moved down accordingly. Most other countries
nowadays don't have subbands-by-mode at all; they just go wherever they want.
Hopefully that won't happen here.
