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.

That video is of an actual real-life coaching session with a person with specific problems. It's not meant to be a generic catch-all "this is how we do it." As anyone who has ever coached or taught any physical activity knows, often you have to over-correct and over-exaggerate certain movement patterns to get the trainee/pupil to realize what the movement is actually supposed to feel like.
From the book:
"... come out of the bottom by driving your butt straight up in the air. Up,
not forward. This movement keeps your weight solidly over the whole foot instead of shifting it to the toes."
"A common error is the tendency for some lifters to drive the hips forward instead of upward. If your hips go forward, your knees will too, causing the weight to shift forward to the toes."
"Likewise, it is common to see the hips shift backwards instead of straight up out of the bottom. When this happens, the back angle will become more horizontal, the hip angle more closed, and the knee angle more open, all in the absence of upward movement of the bar."
"Allowing the back angle to go horizontal on the way up from the bottom produces bad mechanics and inefficient use of the hip and leg musculature."
