All this really means is that the longitudinal orientation is reversed, as you would likely prefer if you were plotting coordinates defined in terms of galactic latitude and longitude, for example. With this keyword, you don't have to resort to tricks with respect to labeling the axes in a custom way or reversing the sense of your data.

Consider this example, with reverse set to 0 or 1:

map_set, /mercator, reverse = 1, /grid, $
xmargin = 5, ymargin = 5, label = 1, /continents, /iso
