More than one battery, or when you want to make sure current flows in a specific direction, or as a voltage divider, or as a safety mechanism... there are a bunch of reasons.

I THINK that what you're seeing there is that the battery on the right is so much weaker than the one on the left that it's getting charged! The current is not only passing through R2 backwards, it's passing through V2 backwards!

And conveniently, you know what the voltage across the battery is: 1.0V! It's written right there on the paper. So it's acting like a resistor!

That said, I've never worked this kind of problem before and right now I'm not in a great position to do the research, so I can't follow up on this at the moment.
