Uniqueness is between case items, not case item expressions

In Section 12.5.3 unique case and priority case

CHANGE

In a unique-case, it shall be legal to evaluate a case item expression at any time after the evaluation of the case expression and before the evaluation of the corresponding comparison. A unique-case shall be illegal if, for any such interleaving of evaluations and comparisons, more than one case item matches the case expression.

In a unique-case, it shall be legal to evaluate a case item expression at any time after the evaluation of the case expression and before the evaluation of the corresponding comparison. A unique-case shall be illegal if, for any such interleaving of evaluations and comparisons, more than one case item matches the case expression. However, more than one case_item expression within the same case_item may match the case_expression.
