Yes but the stretch off pp3/1 is not in any old direction towards the ground - its towards the impact point plane line.
Except with Zero #3 Accumulator, the stretch (Non-Accelerating Thrust) of Extensor Action -- whether executed by Pressure Point #3 or #1 or both -- is not On Plane, i.e., toward the Impact Plane Line. Instead, it is Below Plane -- in the direction the Left Arm is pointing.
