In Toyota hybrid systems, MG2 (Motor Generator 2) is indeed used to drive the vehicle electrically in reverse, as stated by Technician A. Technician B is also correct in stating that the engine may start to assist MG2 if the battery's state of charge (SOC) is low, regardless of whether the vehicle is moving forward or in reverse. This is part of the hybrid system's design to ensure optimal performance and efficiency.
