What does /usr/lib/apt/methods/copy do? I'm sitting in a meeting, idly watching the top processes reported by conky (in Debian Jessie), and it has popped up a few times in the last couple hours.

Both methods can be seen to act the same except that one decompresses on the fly. APT uses them by generating a copy URI that is formed identically to a file URI.
