The 1st pull is vitally important, as is proper starting position, to the outcome of the whole lift. I don't know what Rip is defining as the Deadlift position but this is what I do. I coach all lifters to move the bar inward and upward during the 1st pull.
I teach that the start position has to be one in which the 1)bar is vertically over the base of the big toe, 2)the lifters arms should be vertical and descend by the sides of the knee joints,3)for almost all, the balance at the starting position should be on the forefeet.
I tell lifters to think about making your back and arms look like a crane. Those 3 conditions usually lead to a lower rather than a higher hip position for most lifter's at the Set.
After initiation, the 1)lifter's balance should go to the rearfeet, 2)the arms should angle in towards the lifter, sweeping the bar inward by using a tightening of the lats. This simultaneous shift in balance on the feet as the knees are pushed back and active tightening of the lats produces the inward sweep at the start of the "S" pull. (This inward movement of the bar is absolutely critical to the best lifting. If the arms continue to hang straight down during the 1st pull and the balance doesn't go to the rear, the bar will inevitably be forward at the top of the pull.)
As the bar moves from the floor, the lifter keeps his torso in the angular position of the Set. But, as the bar proceeds upward and inward, a slight tilting forward of the torso occurs just before the initiation of the double knee bend. This is then rectified by the scoop for position and a slight extension of the hips as this occurs, putting the lifter in the correct position at the Launch Point, at which time the hips accelerate tremendously and along with knee extension, drive the bar up and slightly outward in the 2nd pull.
