Discrepancy between CoffeeScript on Node and "Try CoffeeScript"

gistfile1.txt

This CoffeeScript:

name = 'clyde'
do ->
  "Hello #{name}" for name in ['algernon', 'sabine', 'rupert', 'theodora']
name

Complies to this on CoffeeScript under Node:

(function() {
  var name, _i, _len, _ref;

  name = 'clyde';

  _ref = ['algernon', 'sabine', 'rupert', 'theodora'];
  for (_i = 0, _len = _ref.length; _i < _len; _i++) {
    name = _ref[_i];
    "Hello " + name;
  }

  name;


}).call(this);


And this on "Try CoffeeScript:"

var name;

name = 'clyde';

(function() {
  var _i, _len, _ref, _results;
  _ref = ['algernon', 'sabine', 'rupert', 'theodora'];
  _results = [];
  for (_i = 0, _len = _ref.length; _i < _len; _i++) {
    name = _ref[_i];
    _results.push("Hello " + name);
  }
  return _results;
})();

name;

Note that in the Node version, "name" is shadowed, but in the Try CoffeeScript version, it isn't.
