We definitely want a deterministic result for every task execution even if the execution of some subtasks happens nondeterministically. But after rethinking what I wrote last time I would now even strengthen my statement. Concurrency is a structural property of a system, parallelism is property of an (specific) schedule of subtasks and therefore a property of the runtime behavior of a task. Nondeterminism is also a property of the runtime behavior and therefore nondeterminism MAY be associated with parallelism but CAN NOT be associated with concurrency.
