I have spent 2 full days trying to grasp this and this single video did more for me than any other video. I finally understand it. For anyone else possibly struggling with what I was, I did not realize that the newHead assignment is a pointer to a node in the linked list. So if newHead is the fourth node, that node is the same node as the 4 node in head. In short, I did not realize that the variable assignments are basically just pointers.
