It does because that is the way the player is saying he understood Pinnacle's rule and that is his argument to Pinnacle for a "grey area." Going back and saying he now thinks it means something else would say he never was sure what it meant.
If the player were to say he simply didn't understand the rules it would be a case where he should have asked for the meaning prior to the result. As a mediator, I would tell the player, yes, it could have been worded differently but it is clear what the correct interpretation should be and there is no evidence suggesting that Pinnacle hung a rule up that had a double meaning so they could choose which side won later.
