Generating a result which looks like some combination of the inputs, has a little bit of 'Wow' factor if you just look at the pictures and don't think too hard about it. But ultimately its not an exercise in which they can be wrong, and since the image returned is always going to be a face, they'll always kind of be right.
An impressive result would be if they trained their system on the the 300 pictures, and then we're reliably able identify which picture the subject was looking at. That would be quantifiable and testable, and I presume the result would expose that this is all nonsense.
