Test Notifications Appear on iCloud Website

As spotted by MacRumors, it appears that Apple might be testing some sort of notification system on the iCloud website. These banner-style notifications appeared at the top of the browser upon logging into iCloud, but I have been unable to replicate the situation. Apple uses very similar looking notifications in Notification Center on iOS 5, and is bringing the same functionality to OS X Mountain Lion this summer. What do you think Apple is working on?
