Recall the Tailed Beast Bomb requires a balanced ratio of black&white chakras (8:2). While I can't say what they specifically mean by black&white chakras (possibly yin&yang, maybe?) it does present the idea that chakras can be mixed in differing percentages. So my opinion, from either translation is that the ratio of yin release -which by definition "can be used to create form out of nothingness"- is high compared to some other form of chakra (which might be what affects the chakra in the victim's mind). It would actually make sense and those who are better skilled in yin release would be known as the "genjutsu type" that Jiraiya mentioned to Naruto before.
