Wow! Reading these comments shows me that film art is hightly unappreciated. Please see "Last year in marienbad" so that you experience Alain Resnais' masterpiece that is studied in film schools. "Last year..." had similar devices, such as clothes suddenly changing from white to black from one seen to the next. The whole point to film art is to move the audience with cinematic style so as to feel uneasy, fear, sadness etc., and move the story along visually. The artist can embed symbolic elements as homage to others, or whatever his own idiosycratic interests are. That's art. Look at the Mona Lisa painting. What's wrong with it? Why do You keep looking at it? Perhaps the background plays tricks on your perception of her smile/frown? What makes that painting so famous. This is the fun of studying art and the pleasure of discovery. You, the viewer, constructs this outer world. The "interviewees" in this documentary are seeing and creating what the left hemisphere in we humans does -- create meaning through pattern detection. Have fun with their crazy constructions. There's no real meaning here. The artist's creation is and should be ambiguous enough so we create our own personal meaning.
