Do you just saw that last part off and finely sand down the remaining glass nub, or is the video not showing us that final crucial step for some other reason?
thanks also for your prompt answer before.

when you heat just the small thin rod and attach it to the colder marble it is called a "cold seal". only the rod has fluid glass so it sticks to the marble. when you want to remove it you set the marble onto the table or what not, i use a mold, then you lightly tap the small rod near where it attaches to the marble. it breaks right off. it will leave a slight "scar where it was attached. if you hold this area to the flame it melts away smooth.
