I think you may be overthinking this a little, or applying philosophical reasoning where it doesn't quite make sense. If someone writes a book about me, that has nothing to do with me, even if the person who writes the book claims to know everything about me. Only I know what I believe and you should only assume I believe the things you hear me say, whether in word or in deed. EDIT: also, Paul never actually met Christ. He came along later after Christ had already been crucified. If you believe Paul's account, Christ revealed himself in a vision. But everyone agrees that Paul and Christ never actually met in person.
