Pretty close. Wikipedia has a nice diagram of how it works. The Kobo uses power either to change the ink on the screen (doesn't use power to maintain what's currently on there) or in the background monitoring for touches etc. when you have it turned on and for maintaining the volatile part of the memory (RAM) holding your currently open document/book while on or in sleep mode. When powered off it really takes virtually no power since it's waiting on the switch and it doesn't much (if any) to maintain the "permanent" memory (all your books and the Kobo firmware).
