Nice setup and great demonstration. I've been running something very similar, basically using NE tech cord on the back end as a second prusik and a thimble loop on the front end as normal.
I was daisy chaining the back end for a while, and then found myself tying and untying the chain too often, so I ended up using a single butterfly a few feet from the tail. That eventually was replaced with the second prusik, for just the reason you displayed (advancing your TIP).
Running a SRT lanyard is a great way to use a shorter rope length, but the retrieval is the one thing keeping me from using it that way all the time...well, that and the fact that you can get much closer to a stem in a normal side D to side D setup.
