These remind me of other writing techniques (without names) I use to create surprise, leverage presumptions, structure jokes, and even inject new ideas. If you think of someones train of thought like the staves or horizontal lines in musicial notation, but each line is a layer of attention or abstraction, notes outside those lines aren't obvious, but they have a resonance or dissonance with the base ideas between them, and then a sentence or a paragraph can play over them, creating and resolving tension and leading to the conclusion you had hoped to express. A comparative illusion in this view would be something you would use as a transition, for a change of conecptual key, or to bend the ends of an idea into an loop, inescapable without extra cognitive load, and the mind prefers to accept what it is being presented with instead of epstein didn't kill himself. Comparative illusions can have a very hypnotic and distracting effect, and they are an effective tool of persuasion.
