Just a question on interpretation

This one's just a question -- was curious what ya'll thought...

Considering this portion of the Shark rule:

If any Shark has the same Yard value as a Gremmie, it may attack that Gremmie, unless it has already attacked them earlier in the day. Any Gremmie may post a GNDT comment of "Shark# Attack: DICE3 DICEX" where # is the number indicator of the Shark attacking and X is the Skill of the victim. If the result of the first die is a 1, the shark attacks the Gremmie, who loses the resultant roll's worth of Skill.

If the 'DICE3' roll is a 2 or a 3, does that mean that the Shark didn't attack the Gremmie, and the roll can be done again? I'm not fond of this interpretation, but wanted to get your thoughts on it before I tried to go about changing it.

The part that makes me question it is the part that says "if the 'DICE3' roll is a 1, the shark attacks the Gremmie -- that would imply that a roll of a 2 or a 3 doesn't count as an 'attack' and the first sentence says it can attack them again if it hasn't attacked them (I think the intent of the rule is that a die roll of 1 means the Shark injures the Gremmie -- but the words leave some ambiguity in my mind....)

thoughts?
