Isn't the CNN in lesson 2 totally overfit?

Please have a look at: (I included the timestamp, so just that very second)

Now I’m not sure if the images shown in the presentation actually correspond to the real layers of the CNN we’re using. But regardless, aren’t the images good examples for a hopelessly overfit network?
We can see the exact structures of each image in each kernel, down to the exact numbers.
Or am I misunderstanding something about what we’re seeing here?
