Need help getting my hip powered "jab" right

Put an X on your heavy bag. The jab hits the X on an upward trajectory, the right on a downward path. Same spot though. If the second straight punch is down, the next is up. But to the same target.

Thanks grey i still dont understand, lets say the right cross hits the bag at a spot we will label and mark X, then when we come back with a hip powered left jab how many fists distance to the right will the left hit, will it be 0 as in the same exact spot or 1,2,3,4 fists distance over

Also why would the cross come down and the jab up is it cause u slip with the cross

You throw the jab and the punch behind it to the same target, you hit the same spot. the trajectory of the jab is upward for two reasons. First, you don't want him coming over the top of your jab with a counter and that is what happens if you don't jab 'up'. Second, you want to pop his head up and back with the jab so your second punch will hit him on the chin.
When you follow through with your rear hand, it ends up lower than where it started. Where does that put the shoulder of the arm you jab with? So the third punch- the 'jab' powered by the hips turning you back to your starting point, is an upward punch. Keep in mind you are hitting a spot on the bag, but you are punching through it. Do you see?
