That would have been the position when the second bullet hit ar Zapruder frame 224, with Connally's right arm resting on his lap.
He said this was the time he heard the first shot and looked behind him to the right, as he did so his he raised his right arm. But because it was a FMJ round, his body didn't react to the second shot until about ZF232 when he gasps. THis is when "magic bulleters" claim he was hit, his body being in such a postion that a mavouvering bullet is needed to esplain the wounds.
However at ZF224 it is a straight through path.

Frame 223 and 224. Notice the label is pulled outward within two movie frames.
