There is no pick and roll rule. The screening rules allow for a screen to be basically set at the time of contact with allowances for some time and distance. It is also not illegal to go in the same direction of the person being screened. Really hard to say if the call was correct in your game. The issue would be did the screen roll towards the screened player and cause illegal contact or did the roll happen away. You can move on a screen, just have to do it legally.
