No not at all, in that sentence he is talking about human health professionals doing contact tracing rather than apps.
Which is why the thread-starter is right that his argument here is silly. It would be better for him to be clear-eyed that he is biased against technological contact-tracing solutions in favor of human ones, because of his privacy concerns. That is a totally reasonable position! What is not reasonable is arguing against using technology for contact tracing because it has false-positive and false-negative problems; it's true that it does, but all contact tracing solutions are probabilistic in this way.
