You know, I had never noticed before that Gollum fell and then Sam jumped...but then, it was probably a precautionary measure on Sam's part, considering what Gollum was hissing underneath his breath...

I was talking about this thread to my mom and we got into a little debate over it. She thinks that Sam did not have a huge part in Smeagol turning back into Gollum because Gollum was so evil all ready. And then she came up with this idea:

What if Smeagol had never entirely disappeared from Gollum? What if Smeagol cut the Ring from Frodo's hand to save him, while Gollum cut it from his hand to regain his what was once his? What if, as Gollum/Smeagol boasted of his prize as they danced upon the Crack's edge, Gollum danced for the sheer delight of regaining his 'Precious' while Smeagol danced upon the edge with sheer joy that he had saved his master, his Frodo from the doom that had come upon him? It would be that same battle between Gollum and Smeagol that Sam had witnessed once before.
