I a way it's strange that in it's the "powered off"-state the Reader still keeps showing this text because it seems to indicate that in reality it isn't powered off. After all showing that text must somehow use some power by itself, wouldn't it?

The difference between sleep and powered off is that in sleep it will be using a small amount of power to maintain things in the volatile memory (i.e. temporary memory that clears when it has no power). When powered off it has to reload things into the volatile memory which is why it takes longer to start up.
