What is meant by the Jehovah's Witness statement "Jesus was dead, forever dead."?

The following is pulled from an answer to this question: According to Jehovah's Witnesses, In What Way is Jesus Human . > It would appear, then, that the Jehovah's Witnesses believe that Jesus had his own distinctive body and personality, and that Michael had his own distinctive body and personality. What was common to them both was the impersonal life force that Jehovah had transferred between them. And since it was this impersonal life force, and not the individual body and personality, which had made either of these persons the Son of God, the body and personality of the man Christ Jesus was the only one among the whole human race which had no hope of the resurrection, because his life force had been vouchsafed unto the Archangel Michael. And this is confirmed by their saying that "Jesus was dead, forever dead" (Studies in the Scriptures, Vol. 5, 1899, p. 454). The Witnesses appear to believe, then, that the man Jesus of Nazareth was human, fully human, in both body and personality, except that he alone among all of the human race had no hope of the resurrection, because he could not be resurrected as the Son of God, whose impersonal life force had been transferred once more unto the recreated body and personality of Michael the Archangel. The body of the answer describes the creation of the essence or life force of the Son of God as Michael the Archangel and then the passing of that essence to Jesus and then back to Michael. The supposition made within the answer (if I read it correctly) is that, since the humanity of Jesus died when he died and what resurrected and returned to the Father was only a "borrowed" essence, Jesus the man never actually had any hope of resurrection. Is this, indeed, what Jehovah's Witnesses mean by the statement, "Jesus was dead, forever dead" (Studies in the Scriptures, Vol. 5, 1899, p. 454)?
