Repeat: The reason why yin was used in the naming is probably do to the fact that the Yin in Naruto is mental energy, and a big part of the technique is having a quick analytical mind. You could even call it Mind Healing Would Destruction for the heck of it. Some jutsu names are symbolic rather than literal.
