I find this comment, on it's face, very hard to understand. An apparent abundance of qualifiers without definition. Is this an example of circular reasoning?

It seems to me that the text is saying that generalised labour produces value, but then only specific labour produces actual value. What is the difference between actual value and value in general? Is some value somehow more valuable that other? Are we even speaking the same language? Is this just making shit up as you go along and hope nobody notices because the general idea is appealing?
