Is weight shift/bump/slide the moving forward of "turned" hips?

[sifder]

BACKGROUND: I am beginning to execute the chip & pitch with the three different hinges more often than not in my practice sessions. I get it and it feels like no other. The ball flight is amazing, consistently straight and it feels effortless... Distance is great too.

PROBLEM: When I execute a full swing with weight shift, my consistency goes bye bye... when I stick with keeping the weight on my left leg I am golden! I am having a hard time bridging the gap between the pitch shot and the full swing so I am thinking that I have a weight shift problem. Yes? No?

RANDOM THOUGHTS: I am trying to study the weight shift closely to see if this is my issues so I have taken a closer look at the Chapter 1: Basic Motion (Collin Neeman videos) which I am trying to mirror and have noticed when Lynn executes the demonstrations in these video series his weight is planted on his forward foot with ball in back of stance and I don't see him changing his weight distribution when he finishes up with the demonstration of the full swing. But, when I look at this single long iron video and his driver video there is obvious weight shift. i see his left knee driving forward and is weight shifting.

QUESTION:
1. Does the bump or slide represent the moving forward towards the target of the "turned hips" so that when the weight is on the left foot, the hips are still turned and then I pivot? So when I bump forward my hips remain turned they just move forward towards the target direction?
2. After I bump forward am I essentially in the same position I am in at the top of the backswing of the two feet back two feet forward drills for acquired motion after the loading of the backswing like when Lynn has his weight on the front foot?

Thanks in advance for your help!
