 The argument to your call of distinct-values() is a single boolean. If you call distinct-values(true()) the answer will be true(); similarly distinct-values(false()) is false(). Once again, I have to admit defeat in correcting this query. I simply can't work out what you thought it might mean. (Sometimes people find it difficult to explain their requirements either in XQuery or in clear English. If that's the case, it often helps to show the input and your desired output.)
