John is not in the specifier of CP. It's in its case position in the specifier of TP. So it doesn't interfere. I guess the bracketed diagram in the 2nd sentence might be confusing you. I just didn't put the [TP in so the embedded clause is actually [CP [TP John. John isn't in the specifier of CP. (PS. Specifier, not head. These words are not in the heads, they are in the specifiers.)

Thank you for clarifying that. I am eagerly awaiting my copy of the textbook. This series is so good!
