Ya, thats it. The knot that's used for most everything we'd use the double bow for today and that I rag the guys in the group I'm in that they should be using to tie their hosen & doublets. The way they do it leaves one end longer than the other. (bozos) 
Trying to explain how to tie it:
- do a cross-over, passing one under, like you probably do as the first step in tying shoes.
- take the tips of the points between thumb and forefinger of the right hand, making the ends the same length, and pull tight.
- place the index & middle finger of the left hand on top of the tense points(palm down), right up against cross-over. Wrap the points back over the top and completely around under the fingers.
- roll the left hand counterclockwise 90 degrees so you are looking at the palm.
- gently remove the index and middle fingers from the loop while using the right thumb to make and push a new loop of the remaining point into the loop where the fingers were.
- reach over the top and grasp this new loop with the thumb & forefinger of the left hand, keeping the ends of the points still firmly in the right hand.
- work the loop and the ends of the point so the new loop is choked off by the loop the fingers were in and the knot is tight up against the cross-over.
- what you get is a pair of even loops that stay close together, pointed to the left (or up, if tied sideways) and a pair of dangling point ends of the same length going to the right (or down).
- to release the knot you pull the ends like the modern shoelace knot - except it's more secure and takes a stronger tug. Probably why they used it, eh?
With practice, you'll be able to tie this knot as fast as your shoes.
There is another way that involves bringing the fingers under the points and hooking them under while wrapping and then tucking the string between the fingers and drawing the new loop out.
