Besides that ruling is a little ambiguous as written although you might have just used a brief summary. Who is 'aware' of the monster?
I'd say that the wording is bad because "no longer" contradicts "the next time".
Now, why do these wordings (seemingly) contradict each other and what was the intention?
My interpretation: NA version was written after EU 2nd, so there must have been an intended change for the re-wording as a concept to make sense at all.
My strong guess is that they felt the EU 2nd spell was too powerful and they wanted to downgrade it.
Every variable stayed the same except the "how many attacks" variable, which is interpretable.
But the intention must have been to limit it to one attack, which makes me agree with Gold Bearer here.
What they didn't notice was the failure of the second sentence which they bothered to parallelize with their rulebook nomenclature "see",
but made the mistake to include at all, and which seemingly contradicts the intended length of effect for the spell from the first sentence.
The second sentence does have the effect though that the spell can just puff into thin air before it even takes effect,
which Gold Bearer has also pointed out, which makes me fully agree with him.
The contradiction was unintended, the side effect unthought of, but this interpretation is the only one that takes every piece of wording into account in a way that still makes sense as a unit of text.

I think the
Author's Intention Approach to interpreting text is a veeeeery valid one for HeroQuest.
We need it time and time again.
I wrote a rule system
because of it, with a lot of training by Daedalus, by the way.
