Inheritance and Object.Create in Javascript

Question

look at this code :

        var Test = {
        options: {
            name: 'foo'
        },
        name: 'foo',
        init: function (name) {
            this.name = name;
            this.options.name = name;
        }
    };

    var dict = {};

    for (var i = 0; i < 3; i++) {
        var obj = Object.create(Test);
        obj.init(i);
        dict[i] = obj;
    }

i don't understand why all the properties in dict[X].options.name in the object dict has the value same value(2) and the propertiesin dict[X].name has different value ?
