No, I don't think so.
You want to keep your weight on mid foot and the wider you stand, the more you want to push out to the sides.
I also think that hip drive the way Rippetoe explains it is bad for most lifters, at least for the raw lifter.
However, a lot of people tilt their body forward and are afraid to keep the straight up and down when they get close to their max. What happens is that the weight gets over their toes and the bar path shift forward right at the bottom.
Stand erect before you descend and try not to lean forward too much.
^ I was about to argue with this then I saw the description of the video:
Note : Starting Strength the book varies from Rippetoe's demonstrations. The language of the book is for the most part correct, but the execution of the demonstration videos by Rippetoe is the issue.
In the book he recommends pretending that someone is pulling on your lower back with a chain straight up, not leaning back like that guy is saying in the video. BTW, have you read starting strength? I see you knock it a lot in here but I've found it to be the single best thing on fitness I've read. It's fixed a lot of form problems I found myself with when I was starting out; went back and re-read the section and found a solution to whatever issue I was having at the time.
Those quotes from the book are sound advise, but when you look at some of the videos where Rip teaches people to squat, they do exactly what he mentions in your 3rd point; hips go up first and the lifts becomes sort of a weird mix of a squat and good morning. This puts a lot of unnecessary pressure on the lower back.
Maybe he intentionally over exaggerate the movement for beginners, like you say and if that leads to good and safe form later, it's all good.
Imo, his own squats in this video has the butt rising too fast. If you look at top level powerlifters and weightlifters most of them keep a more vertical torso.
