Yes.

Well you knew about the -daystart option to find, which I hadn't
encountered before, and xargs -I %, which is fairly advanced, so you
obviously do know quite a bit!

Anyway, the construct $(...) in the middle of a command means to run the
command inside the brackets and then use its output as an argument to
the outer command.

Looks like it to me. I'd first run it with echo before the cp, so you
can see what it would do and sanity check it.
