:Oh, wait. I was reading the coordinates like it was a cartesian plane, like on a Lambert or Mercator projection. But in retrospect this is some kind of elliptical projection ({{w|Robinson projection|Robinson}}? {{w|Winkel tripel projection|Winkel tripel}}?) such that the longitude lines are bowed out, further as you get away from the center (here 90°, I guess). That is...too hard for me to read with precision without doing too much math and drawing lines (so I guess I'm lazy), so, probably it's just fine? I dunno.

I just quickly put together an abs(longitude) "projection" image based on a real (public domain) map, to show what this would look like more realistically, with overlap. Are home-made images allowed? I cannot upload though ("You do not have permission to create new pages"). Is this because I'm a new user or are uploads prohibited for most users?
