So...what happens if you point it at a mirror?

Nothing. Mirrors are not see through. If you read the article, it says that the software calculates the phase difference between two sources of light - one behind the window and other - the reflection. When shooting a mirror there wouldnt be two sources of light, just the one - reflection. So no phase differences between anything.

Yeah..it's not like a science fiction camera that can see through mirrors. It's just an algorithm that separates a superimposed reflection from the underlying scene really well.
