//1. use $on and $emit to pass param between pages:
$rootScope.$on('click-different-links-finally-get-last-same-page',
  function(from_url) {
    $scope.from_url = from_url;
});
$rootScope.$emit('click-different-links-finally-get-last-same-page',
  '/router-urls');


//2. in the last page, define the click event to return previous page
// whichever it comes from:
angular.module('testApi', [])
 .directive('testDirective', function() {
  link: function(scope, element, attrs) {
    element.click(function($event) {
      $event.preventDefault();
      attrs.$observe('from_url', function(value) {
        $timeout(function() {
          scope.$apply(function() {
            $location.path(from_url);
          })}, 1);
      });
    });
  }
});
