[DR] I suggest the following simplified wording for the whole paragraph

For nonintegral and aggregate expressions, if cond_predicate evaluates to an ambiguous value, then:

- if the logical equality of comparing the first and second expression's value is true, it returns that value.

- if the logical equality is not true, it returns the default uninitialized value for the type of the expressions.

[DR] Also need to change an earlier paragraph:

From:

If cond_predicate is true, the operator returns the value of the first expression without evaluating the second expression; if false, it returns the value of the second expression without evaluating the first expression. If cond_predicate evaluates to an ambiguous value (x or z), then both the first expression and the second expression shall be evaluated, and their results shall be combined bit by bit using Table 11-20 to calculate the final result unless either the first or second expression is real, in which case the result shall be 0. The first and second expressions are extended to the same width, as described in 11.6.1 and 11.8.2.

To:

For all expression data types, if cond_predicate is true, the operator returns the value of the first expression without evaluating the second expression; if false, it returns the value of the second expression without evaluating the first expression. If cond_predicate evaluates to an ambiguous value (x or z), then both the first expression and the second expression shall be evaluated, their results shall be determined as follows.

For integral expression data types, their results shall be combined bit by bit using Table 11-20 to calculate the final result unless either the first or second expression is real, in which case the result shall be 0. The first and second expressions are extended to the same width, as described in 11.6.1 and 11.8.2.
