The screensaver doesn't mean the Kindle is actually in sleep mode. It doesn't immediately go into the power saving mode as it may be busy with other operations like music, TTS or indexing. If none of those tasks need to be run or are running then it will go into low power mode after a preset amount of time and which point it is still using power to maintain the contents of RAM. In this mode, it is unresponsive to keypresses except the power button which will wake it but there is also a timer which will periodically wake the Kindle to make it check in over Whispernet.
This is why the battery life of the Kindle 3G+WiFi is significantly shorter than that of the WiFi only model even if it is kept in standby mode.

Actually, it does do that. That's what hibernation is. That's why you can turn your Kindle off in the middle of anything and when you turn it back on you'll be at the same place you were. Tasks and processes are temperarily suspended (most of them, at least) and are resumed upon waking. And as I said, it doesn't go into sleep mode immediately. I said it waits to finish certain tasks before hibernating. I never said that screensaver mode was indicative of hibernation or standby mode.
