Sometimes it's difficult to understand Google. A few weeks after dropping the non-obvious navigation menu from the desktop UI, Google tests a new mobile interface that uses the same menu.
Cascading menus on a mobile device? They're too large and many Google services are missing (Reader, Blog Search, iGoogle, Product Search, Google Finance, Picasa Web, Google Talk, Google Tasks), not to mention that there's no room for displaying Google+ notifications.
