My statement covers both.

If the motor is operating below 70% slip it is not developing full torque.

When the motor slips too much the internal cross bars in the rotor start to operate on higher and higher inducted frequency. The problem is the stator is almost always designed to run at peak efficiency well under 10Hz.
Increased slip just creates more heat, not more torque.
