No... it's simpler than that.

The copy-data request is a shortcut for read followed by write, just without the data transmission. The server should internally do the same thing that would happen if one did a "read" from the source, followed by a "write" of the same data that "read" would transmit on the wire. No need to prohibit or dictate anything with regard to how the two file handles were opened.
