well since we haven't had a PiL arguement for a while

;
I am with epee scherma, that looks like an attempt to establish PiL rather than a simple attack - movement stops after the arm is extended, there is no footwork forward (the simple attack as a lunge or step forward) or backward (to get tempo for PiL).
So even if it was a simple attack by the right it is;
Right; attack, hesitation (or just attack no).
Left; takes up the action and scores.
(and since we are now into disclaimers; I have no credentials of any sort).
