No, this is an entirely different tech stemming from some bad patch coding.
Basically, to explain it, Bane's old dash used to be hot garbo, but it still had all of the cancel properties the other dashes did.
When they made it better, the new dash could also be cancelled, but they never got rid of the old cancelling frame work, so Bane can cancel his dash is two places: At the 11 frame mark, and at the 8 frame mark.
Bane's dash is exactly 15 frames, 11 frames of dashing with 4 frames of recovery. One of the better dashes. Now dashes can be cancelled into two things: Specials and other dashes.
Bane's dash is different, because you can input other things into it. f.2 being the most notable one, and f.2 dashing being the same speed as normal dashing despite the start-up frames of f.2 is a key part of it.
You can actually cancel it into something like a d.1 which puts Bane in a ducking state with almost no recovery time on it.
A wave-dash can be created using this, having Bane do something to the effect of f.2-dash-d.1-f.2-dash-d.1. This can be further improved by cutting out the f.2 (though its harder to time).
I've gotten about 4 reps, though my equipment can't work with my new computer so I can't show it off
Mind you, this is just framed, but you are basically cancelling the dash 3 frames earlier into another move.
This can be done to make Bane's backdash safer too, especially against people like DD, by doing backdash cancel into b.1 Since b.1 is +3 on whiff with only 9 recovery and 12 active frames.
For the sake of it though, this has a purpose in the discussion because instead of Bane jumping forward for 15 frames and then ducking, he is instead ducking on frame 8 but covering mostly the same distance.
