There is no such thing as LTE. Its a Myth!
This looks like a classic RH pedal turn in a B212/412 (Torque Turn) followed by a failure to enter sufficient left pedal (power Pedal) to stop the yaw.
There is not a helicopter built that the yaw cannot be stopped if sufficient pedal is applied.
There are no aerodynamic conditions that equate to LTE or TR Stall.
