I reviewed that Brain Manzella video. Although he uses the term "snapping the kinetic chain" what he actually describes has nothing to do with a kinetic chain. Because I do not believe that the kinetic link model theory has applicability to the full golf swing, I could explain what he is saying without referring to the "kinetic chain".

He is basically stating that it is important to hit against a firm left side. I also believe that it is important for two reasons.

1) If one braces the left leg in the downswing, and creates a "firm left side", then it stabilises the position of the lower spine during the mid-late downswing. If the head is kept back (so that the left side of the face doesn't get nearer the target) during the downswing, and one limits forward movement of the lumbar spine, then one creates the secondary spinal tilt that is necessary for the upper torso to rotate properly in the downswing - with the right shoulder moving downplane. That's a major factor in controlling the directional approach of the arms in the mid-late downswing.

2) If one braces the left leg in the downswing and prevents left-lateral swaying of the pelvis, then the upper torso and arms can rotate with more controlled power and allow for a solid compressive blow at impact. It is similar to a boxer who hits a knockout blow with his right arm driven to full extension. If the boxer doesn't brace his lead leg and lower body, he would simply fall-into-the-strike and all his potential strike-power would be lost.
