The rationale in the interpretation isn't about making a takeoff or landing, it's about acting as a required crew member for the duration of a flight. On a multiple-leg flight with each leg more than 50 nm from the point of origin, cross country time may be loggable for each segment. If the safety pilot is a required crew member for one or two segments, but not all, those segments for which the safety pilot remains a required crew member for the entire segment (not just a part) may be logged as cross country. Nothing in the legal interpretation prohibits this, but in fact, the interpretation supports it.

Note the relevant language: "However, Pilot B may not log any cross-country flight time because that pilot was a required flight crewmember for only a portion of the flight."
