There is nothing unexpected about this choice. Most people see the cube from this perspective. It gets interesting when I then ask them to pick out the other front face. Most of the time, people pick out the sides of the cube above but a smaller number of people pick the cube below, as I had primed them to look for it, just as the narrator had primed viewers of the gorilla video to watch for how many times the white team passed the ball. If I had asked you to see if you could spot the gorilla in the video you'd have had no problem with that.
