How to do it 
As the clone get lifted, she revert her right leg then gather energy in her thighs to perform an equivalent high jump to match the height the clone rise to. Now in the air she position herself to face the upside down clone [I don't think there is any nEed for the feint high kick in this situation], she use her left leg to perform a straight forward low kick at the clone hitting his ribcage then she direct her right leg to meet his waist, she control her force impact so he doesn't fly off or out of range yet, she continue to perform a series of low and high kicks targeting his torso region; satisfied with high kicks and low kicks effect she kick him hard with her left leg sending him crashing into the ground. She proceed to cease her motion in air and land back to the ground with legs first.
