In Toyota/Lexus hybrid systems, MG2 (Motor Generator 2) is indeed used to drive the vehicle electrically in reverse, making Technician A correct. Additionally, if the battery's state of charge (SOC) is low, the internal combustion engine may start to provide power, including when the car is being driven by MG2, making Technician B also correct.
