I remember reading an article of the difference between 2 year olds and 3 year olds. A two year old will see a picture of a shoe and try to put their foot in it whereas a 3 year old realizes that the picture is only a picture.

I imagine the 1 year old in the video is also falling into the 2 year old trap. But as people have commented this is just how learn and how our brains develop.
