Yes, that's exactly what he's saying. He did not remember that he had stringently affirmed those propositions to be "all true" back in 2007. Upon seeing them again yesterday, he immediatly said they were "utter nonsense" and "metaphorical". Since those Malthusian-style propositions of Darwin's are the the very foundation of Natural Selection, js1138 is thus saying that Darwinism is either utter nonsense, or a metaphor.
Since truth is a word best avoided in science, then it makes perfect sense.
