Yup. The word "clone" is faster to type because it has 4 letters less than the word "duplicate". Also, cloning may be done without rman, using SAN. The "duplicate database" command is an rman command. If you decide to use SnapVault (NetApp) or SRDF (EMC) for cloning databases, RMAN will not play a major role.
