Holy crap that is cool

The link above the video has a tutorial but I can't visualize it.

I think it's the same as this.

Double Fluke Rig / Donkey Rig / Tandem Rig:

Seems fairly simple to me 

What keeps them from swimming together? (Side by side)

Those eels are too cool!!

As far as watching the double fluke rig.... After 3 1/2 minutes of watching the Guy tying knots? I gave up hoping to ever see the Rig swim.

Looks like you tie a jig head to each end of a piece of 3' leader material.  I don't know how critical it is to get the loop in exactly the right spot along the leader, but if you end up with 30" of line after tying knots, you would just tie a loop in the leader 10" from one of the jig heads.  If you pick the whole thing up by the loop and let it dangle, the bait (rigged with the eel or whatever) on top should be completely clear of the bait on the bottom.
