In plain language
If you are flying multiple drones and one has an emergency, and you cannot safely manage the emergency while monitoring the other drones, you must immediately land the healthy drones to prevent accidents.
Requirement as structured
MLIT states that if a pilot cannot simultaneously handle an emergency on one aircraft and monitor other normally operating aircraft during multi-UAS operations, they must make the normally operating aircraft make an emergency landing to prevent accidents.
