Looks like the Porsche pushed off the track, either apexed wrong or lost grip. He then looks like he is guiding the car back on easy, and then either it hooks more than he thought it would, or he was trying to get back into a racing line and didn't see the other car. Maybe he could have gotten back on the track more gradually. Looks like maybe if he lifted to slow down, he it would have helped. I don't think lifting would have caused a spin cause he wasn't really turning at the point where lifting would have helped.
