In the header of maps, this flag tells the game the length of its preview's X-axis in pixels, i.e. its width in 2-dimensional image terms.
On saved random maps, Width also gives the "width" of the map in the sense of its length from east edge to west edge (i.e. diagonally from top-right to bottom-left). This is done on a scale from 1 to 5, with 1 signifying a small map, and 5 signifying a very large one. Presumably, this is done for automatic selection of maps in quick matches or something similar. (iow, so a user can select he would like to play on a "large" map, for example.)
This value cannot be set manually - it is determined automatically by the Random Map Generator.
