The statement is true because reversing the direction of rotation in a three-phase induction motor can be achieved by switching the connections of any two of the three phase supply leads. This action changes the phase sequence of the motor’s supply, thereby reversing the rotating magnetic field created by the stator. Since the rotor of the induction motor always tries to follow the direction of the magnetic field, reversing the field results in reversing the rotor's direction of rotation.

In contrast, other scenarios mentioned, like single-phase motors or "depends on the motor type," don't apply here. Single-phase motors operate differently and typically require additional methods for direction reversal, such as changing the polarity of the auxiliary winding or using a specific starting mechanism. Thus, the straightforward principle of swapping leads affecting the direction is unique to three-phase induction motors.
