Nothing: with the default mesh file format (MSH, version 2), Gmsh renumbers the nodes and the elements when writing the mesh file. Just open the mesh to check what has been saved. The next version of the format (MSH, version 3 ; already available but still experimental) will not renumber anymore by default.
