I saw it, and indeed it went by really quickly. What I saw was a mass
hung from a lower pulley. A rope attached to the lower pulley going
up around top pulley #1, back down around bottom pulley, and up
around top pulley #2, with the top pulleys ganged (if I remember that
term correctly.) Thus there were 3 supporting ropes for the lower
pulley, hence a mechanical advantage of 3.
