Nice catch. Meanings, within meanings, within meanings. Typical occult paradigm. It's twofold. It allows them plausible deniability and it fulfills the free will doctrine that is required with informed consent. Doesn't matter if you understand what's being said. Speech, thoughts, and written words have their own frequency. Thus why you can speak something into existence. Studying language formation with a mind to the occult gives one deeper understanding in why specific words are used in the ways they are and how they came about.
