> (i.e. we expand the land in the north more than the south

Yes. This is a consequence of the fact that the "land in the north" is, on average, further north (of the Equator) than the "land in the south" is south (of the Equator).

The southernmost point on the South American mainland, per Wikipedia, is Cape Froward, Chile, at about 54°S. For perspective, some cities between 53°N and 54°N include Edmonton, Alberta, Canada; Hamburg, Germany; and Dublin, Ireland. Similarly, the capital of New Zealand is about in line with the capital of Albania, and the capital of South Africa is about in line with the capital of Qatar.
