"Extensor Action" is simply the maintenance of the integrity of the Flying Wedges, as assembled at address. It is neither optional in its application or variable as to which arm you feel the need to extend.

The right arm has to have its tendency to straighten controlled by the "check reign" effect applied by the left arm.

Aint' that the simple truth?

Homer thought so too. The rest, is history.
