Why Does Rotor Speed Increase in High Slip Region After Max Torque in 3-Phase Induction Motor?

Hi,Query: Torque speed and Torque slip characteristicsReferring to the Graph attached with this post...In the High slip region (Colour:Green) following are the conditions after Torque achieving its maximum-
1. Torque  value decreases2. Slip value decreases &3.Rotor speed increases
How it is possible for a Rotor to increase its speed upto Synchronous speed when it is loaded to its maximum?
When a motor is loaded more than its capability the speed should drop. But this is contradictory referring to the Graph.Kindly help me out to understand better
Thanks in advance

Beyond the maximum torque point, the value of the torque starts to decrease. As a result, the motor slows down and stops. In this phase, the overload protection must immediately disconnect the motor from the power supply to avoid damage due to the motor overheating.
