stress on the left arm

[HungryBear]

I am very troubled by the words.

....overlapping as opposed to sequenced release, .......... An uncocking of the #2 down but on plane, the left wrist turned to the plane. An uncocking followed by a swivel,.........

It is my understanding that no accumulator is completely released until follow through and #2 can not be released before impact because the rifgt arm unfolding regulates #2 release. ?????
