As far as the understeer goes, keep in mind that the driver wasn't complaining of excessive understeer. The only real comments in that direction is that the front would wash out just a little on throttle. It's a feedback loop. Earlier in the weekend, he wasn't complaining of oversteer, but I could see the maintenance throttle pick up of 5-10% in places. I then just started increasing rear grip (increasing understeer) until that went away. What I was left with was a driver that would go to throttle like you see in that second chicane. The time between 0% and 100% was pretty small.
I liked this. You've given the impression that you changed the settings of the car without him knowing. Do you do this kind of thing often, or do you slip it in while changing something else unrelated? I imagine the human nature is more likely to make a driver reject change if he in turn has to change his style a bit, otherwise has no complaints and did not request the change.
