It is a thought and has nothing to do with how this particular entity has been implemented. What I got from the post was that dyslexic people see words/letters differently than us. And maybe there is a way to balance that out with deterministic enforced shuffling (edit: don't take shuffling literally). That is why used the word "train". I don't think anyone except a person with dyslexia knows what the "patterns" are, if any. The patterns could be different for every person too.
