Imo
I dont think so.
my definition of accum #3 is the rolling of the left arm accentuated by the left shoulder turn. This is passively felt at PP#3.
When the angle between the club and left hand is zero, I feel no transfer of power at PP#3 simply because as hard as i might roll the arm it does not rotate the clubface.
Holding the club along the lifeline of the palm makes it very difficult if not impossible to rotate that clubface.
