Mr.X,
I assume the popper floats... as is the want of a surface lure. In this case the pulley isn't necessary. You can tie on a dropper on a single piece of line, even thinner diameter than your mainline... just use a surgeon's join (triple overhand)... no big ass blood loop required. Of course the pulley will give you an advantage of better control over your expensive popper if the eel gets hit.
As for the pulley, the principle is the same as the other pulley rigs... to lift the heavy thing up and out of the way of snags. the pulley rig is a rough ground rig and the weight of the fish lifts the lead up out of harms way.
