My *guess* would be that one of packages other than Statistics`DescriptiveStatistics` has added additional definitions for ExpectedValue without modifying the help message provided by Statistics`DescriptiveStatistics` for ExpectedValue. I haven't actually reviewed the code inside the packages for ExpectedValue to either confirm or deny my guess.
