> They should have gone around at 1000 feet

They hit the ground at 158 knots. 767-300ER rotates at 130 to 160 knots. Given it had burned through its fuel, at the moment they touched down they could have immediately taken back off and gone around.

Given the pilots braked at 146 kts, released at 120 kts to throttle up for G-A, then four seconds later ditched the G-A and re-applied brakes, this sounds like they got stuck between going around and committing to the landing and never quite did either.
