Okay, I've been working on it. And here is what I did.
I recorded the commands on training mode, then I tested it against myself, yeah I couldn't block it, so that means I didn't miss the thing. Alright now what I tried was
Mash on the roll button: I was able to roll escape it on occasions, but that kinda sucks because as I roll I can get 2Ked into a combo.
Do an LDM: Some LDMs were able to break through it.
So thankfully this thing seems to be breakable thus far, hopefully

. It is still a pretty darn nice trap. And I don't think my execution doing it was the cause of me being able to escape it by myself

.
And if it was my execution doing the thing the cause of me escaping it, then I have no idea.
EDIT: GRAGH! I noticed I can't roll escape on the first repetion, but only on the second, same with LDMs... And when I looked closely at my record, I notice I do the second one a bit slower than the first one.. SO DAMN, I bet I was only able to escape it cuz I missed the timing. So after all this thing could have tight timing.
EDIT 2: I'll like to label this as escapable for now, but just as a darn nice reset unblockable trap.
