I guess, what would be the area that defines a lie? Is it directly under the ball? If so, then I believe his lie was not disturbed since he was able to place it then asked for the official to confirm if he could rake the bunker.
14.2d(1) says that when replacing a ball that had been lifted from sand, the original lie MUST recreate the original lie as much as possible. Raking away the footprint did just that. I'm not sure that the pre-2019 rules had the same requirement.
As for whether the raking made the lie better or worse, I think it made it more predictable. I doubt that Phil practiced bunker shots with a footprint right behind the ball.
