Seems to be no different than how people memorize "facts". I'm watching my daughter learn shapes right now. When I see a square, I call it a square and look for a matching "square" piece. It seems when my daughter sees a square, see is still looking at it's properties, labeling individual attributes (pointy thing here), then trying to find the same attributes on the corresponding piece. Eventually, my daughter will see a square enough that the concept will be re-enforced in her mind as a square. I wonder if a similar behavior is happening here. This specific image was presented enough times that it essentially "burned into" the AI. Rather than having to attempt to generate this image from scratch, the AI will simply pull out the canonical reference.
