Everyone here argues whether the outcome was coincidence. Nobody asks it of the glyph.
Take one sentence of intent. Do your usual letter reduction and draw it. Put it away. A week later, reduce the same sentence again without looking at the first drawing. My bet is the two shapes share almost nothing, because the reduction is full of legitimate choices: which letters to drop, what order, how to join the strokes.
If two honest drawings of one sentence look unrelated, the shape isn't carrying the sentence. The sentence is, or the attention you paid it while drawing. That is a focus tool and nothing more (which is fine, tools are useful).
One sentence is n=1. I want ten sentences, two drawings each, then a stranger who has never seen the sentences shuffles the pairs and tries to match them. Chance level is simple arithmetic. If strangers beat it, I'll eat the word placebo. Anyone got pairs?
No one has stepped up yet.
