Well there was a huge discussion on what it means amongst judges. On plain reading it does not do what it states it does. Start just with the phrase "its spell" - those words are entirely undefined until getting into the rulings, and don't mean what they mean in other contexts. It makes no mention of the prior rules that it sort of hacks into this either.
I have no idea what rule 722 has to do with prepared.
