The projection of a vector or raster map is the projection of the current GRASS location. The only reason I can think of for storing the projection info in the vector head file is when a vector is packed (v.pack) for export and unpacked (v.unpack) into a new location. But 1) the projection is not stored in the vector head file which does not make sense anyway in normal operation, 2) v.pack and v.unpack could store e.g. a proj4 or WKT string in the package and check upon unpacking if unpacking is legal.
