A reasonable observation. It was a once in a lifetime opportunity for most people in Dealey Plaza to see Jack and Jackie up close. Who is going to look at them in their peripheral vision? But Andrew is so desperate to save his silly theory that he'll come up with anything.
I am not suggesting that she is looking at JFK. You are saying she has to be looking where her hood is facing, which may be the QM or the VP car. I am just saying I don't know where she is looking because I can't see her face.
When she turns her hood and head at z202, she can't be looking at JFK. But I still can't tell where she is looking so I have to defer to the evidence. She said that when she stopped running she turned and looked at the roof of the TSBD and saw pigeons flying away from it. That fits with the position of her head at z202-206.
