window.location.search available only in rendered() callback?

We're trying to access window.location.search but after routing, it is available only in rendered() callback and not in created() callback. Is this by design? We're having some difficulties because of this behaviour. The sample code below demonstrates it. After clicking the link here http://localhost:3000/hello?param=val The console output of hello2 template shows:

hello2 created: ?param=val
hello2 rendered: ?newParam=newVal

Shouldn't the newParam be available already in created()?

Router.map(function () {
    this.route('hello', {
        path: '/hello',
        template: 'hello'
    });
    this.route('hello2', {
        path: '/hello2',
        template: 'hello2'
    });
});

if (Meteor.isClient) {
    Template.hello.events({
        'click #link': function (e, t) {
            e.preventDefault();
            Router.go('hello2', null, {query: 'newParam=newVal'});
        }
    });

    Template.hello2.created = function() {
        console.log('hello2 created: ' + window.location.search);
    };
    Template.hello2.rendered = function() {
        console.log('hello2 rendered: ' + window.location.search);
    };
}

<template name="hello">
    <h1>hello</h1>
    <a href="#" id="link">Problem?</a>
</template>

<template name="hello2">
    <h1>hello2</h1>
