That technique works if you're good at remembering long phrases/stories/quotes verbatim. Not everyone has a memory works that way. I've tried mind palace style and mnemonic techniques, and I will always remember the general gist, but typically not the exact order and specific words used. Same issue with reciting quotes. I can just about remember the 7 word phrase that I use to unlock my password manager, and I still sometimes mess it up. Similarly I can never remember the plot of films more than a few days after I watch them - though one great thing about that is you can always re-watch films like they're new. Yet simultaneously, I maintain a working memory of several programming languages/frameworks, and otherwise generally have a good semantic memory.
