That clearly isn't referring to concepts in the way we use them, considering it specifically says "but we still need to treat it as something real.", which indicates that it's talking about concepts-as-ideas, and not concepts as Forms. In addition to how it can be developed, which if you want to argue that the soul is a concept rather than a sense of self, would be another knock against the idea that it is form like given that it can somehow come into existence not just after its particular, but as a result of it's particular existing.
Tldr; No this isn't the type of concept we use for concept manip, this is clearly using concept in the sense of an idea, and even if it were somehow a concept, it wouldn't even be type 3, it would be what the old type 4 was
