The bullet entered the right forehead, lifted up the Parietal bone, creating extensive fractures and
ultimately exited the Occipital bone. The autopsy photo matches frame 313 quite predictably.
Dr. Grossman clearly states that the hole was too large to be an entrance wound, because the large irregular hole was a wound of exit.
The back of the head was lifted up to demonstrate the large wound on the right rear. Frame 313 and the autopsy report jibe nicely to produce a factual basis for the rear blow-out witnessed by forty or so folks, including Jackie and the driver.
Instead of completely lying, Dr. Humes simply understated the missing skull in the Occipital region which the hole was most dominant.
Lastly, Dr. Grossman describes perfectly the confusion about whether a hole exited in the Parietal region:
"It was clear to me that the right parietal bone had been lifted up by a bullet which had exited." There was no hole on the top of the head. It was on the right rear and likely the top back/Parietal, not the very top.
His hair and skull is clearly lifted up in the second skull image, thereby corroborating Grossman's accurate view of the wounds.

Missile Wounds
1. There is a large irregular defect of the scalp and skull on the right
involving
chiefly the parietal bone but extending somewhat into the
temporal and occipital regions. In this region there is an actual
absence of scalp and bone producing a defect which measures
approximately 13 cm. in greatest diameter.
