^^ you are correct sir. Tech stuff below.
From Wikipedia:
"If there is no additional coupling on over run, the LSD is 1 way. This is a safer LSD: as soon as the driver lifts the throttle, the LSD unlocks and behaves somewhat like a conventional open differential. This is also the best for FWD cars, as it allows the car to turn in on throttle release, instead of plowing forward.[2]
If the LSD increases coupling in the same way regardless of whether the input torque is forward or reverse, it is a 2 way differential. Some drifters prefer this type as the LSD behaves the same regardless of their erratic throttle input, and lets them keep the wheels spinning all the way through a corner. An inexperienced driver can easily spin the car when using a 2 way LSD if they lift the throttle suddenly, expecting the car to settle like a conventional open differential.
If the LSD behaves somewhere in between these two extremes, it is a 1.5 way differential, which is a compromise between sportiness and safety."
