Yes sir, you got it.
NOTE: The prusik cordage must be pliable enough to grab the rope in case of ascender failure... Try this; Push the ascender up against the prusik and keep it there, disengage the cam and pull down with the ascender. The prusik must grab and hold, with zero slippage. Cordage and 'cordage length' are key to this set up. What may work as a friction hitch length, may NOT work in this set up.
At the Wisconsin TCC, 3 years ago, a Master's Challenge climber was gonna use this method. I asked to see the set up and then did what I explained above. The prusik failed to grab at all. The climber then wanted to do it, and it did the same thing. Needless to say, it wasn't allowed.
