They mention it's used in oral literature as an aid to memorization. It can also be seen as a human error-correction technique, just like a transmission over a noisy channel this allows the text to be preserved using oral transmission over many generations.
There are many other literary techniques which can be seen in the same light, the simplest of which is rhymes. There's also alliterations, verse-lengths in poetry being restricted to the right amount for chunking, anadiplosis, chiasmus in a more general sense...
I've been working on a series of texts that combine these techniques with mnemonic systems to try and achieve super-human speed in vocabulary acquisition for fun but they're really hard to combine into a text that is somewhat natural.
