Sorry about that, thought we'd posted already!
If you see a theme published with the title "Copy of" and
same/similar colors, it's probably because someone else saved the
copy privately first and then made it public. At least with the
words "Copy of" in the title, you're able to at least tell the
difference more often now between which theme is most likely the
original and which theme is a copy. Periodically, we convert
similar copies that are public to private to help avoid confusion.
