Here's the key phrase you should really be bolding:
to protect a religious view from what the Board considers to be a threatThe "remind schoolchildren" part isn't a problem, and the judge (and Constitution)) wouldn't have any problem with it if that had been all the "disclaimer" was. However, what you're "forgetting" is the rest of the testimony and decision, which overwhelmingly demonstrates that the clear intent and result of the "disclaimer" and "ID textbook" was, and I quote, "to protect a religious view from what the Board considers to be a threat". *That* is the part you should boldface when you quote that passage, because it's the key phrase, the one that makes the "disclaimer" unconstitutional. Read the whole decision (instead of the creationist websites and their spin) if you're still unclear.
