If we were talking arthropods, the distinction would be significant. Since we're not, I think it's really just a quibble.

I don't think that it is semantic. Evolution by natural selection is about changes in gene frequencies in populations. While it's true that our genes share a genetic vehicle (a person), it is the genes that are passed down (and not all of them) via sexual reproduction.
