That's the way the Google Map code works. Try it with the Earth and
you'll get the same effect:

http://maps.google.com/maps?q=90210&ll=34.0,-118.0&spn=180,360

But if you're more familiar with Earth geography than Mars you're more
likely to recognise the part of the Earth that gets tiled.

The code works that way so that you get something sensible if you zoom
in 3 or 4 levels and look at a part of the planet near the International
Date Line (or whatever the Mars equivalent is).
