My personal interpretation is that Shojo's account necessarily conflated different events because the Sapphire Guard lacked a key piece of information: the existence of more worlds between the original one and the current one. So they knew that the Snarl destroyed worlds, but they thought only one such world had existed, so the obvious assumption was that the Snarl destroyed the original world. That's what the crayons showed. In reality, the Snarl would have destroyed every world except for the very first one, the four-quiddity one.
