Based off my previous example from your earlier question

This is what you say you want: working example with multiple routes

code snippet:

var map, ren, ser;
var data = {};
var data2 = {};
var marker;
var infowindow;
var doMark = true;
var directionsDisplay;

var wayA = [];
var wayB = [];
var directionResult = [];

//Função de Inicio

function goma() {

  var mapDiv = document.getElementById('mappy');

  var mapOptions = {
      zoom: 12,

      center: new google.maps.LatLng(-23.563594, -46.654239),
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    //Cria o mapa do google, coloca as definições do mapa, como tipo de visualização, pode ser ROADMAP, SATELLITE, HYBRID, TERRAIN
  map = new google.maps.Map(mapDiv, mapOptions);


  var control = document.createElement('DIV');
  control.style.padding = '1px';
  control.style.border = '1px solid #000';
  control.style.backgroundColor = 'white';
  control.style.cursor = 'pointer';
  control.innerHTML = '<img src="http://i47.tinypic.com/2dlp2fc.jpg" border="0" alt="Image and video hosting by TinyPic">';
  control.index = 1;
  map.controls[google.maps.ControlPosition.TOP_RIGHT].push(control);

  google.maps.event.addDomListener(control, 'click', function() {
    doMark = false;
    markNow();
  });

  google.maps.event.addListener(map, "click", function(event) {
    if (wayA.length == wayB.length) {
      wayA.push(new google.maps.Marker({
        draggable: true,
        position: event.latLng,
        map: map

      }));
    } else {
      wayB.push(new google.maps.Marker({
        draggable: true,
        position: event.latLng,
        map: map

      }));

      //Renderiza a rota, o draggable é diz se o waypoint é arrastavel ou não
      ren = new google.maps.DirectionsRenderer({
        'draggable': true
      });
      ren.setMap(map);
      ren.setPanel(document.getElementById("directionsPanel"));

      }, function(res, sts) {
        if (sts == 'OK') {
          directionResult.push(res);
