That's correct (and the primary reason for having to book by phone rather than directly online).
It's worth remembering that there's no advantage to booking a roundtrip award ticket over 2 one-way awards. For example, if you'd prefer a stopover in Japan in one direction, just book a one-way award using JL in one direction, and book a separate one-way award with CX (with a stop in Hong Kong) in the other.
