Accidentally did this during my first playthrough. I'm able to walk while healing. If someone figures out how to consistently replicate this behavior, it could be useful for speedruns. Figured I'd post this here in case someone with more technical knowledge than I could figure it out.

I think I MAY know how this happened, from what I see, it seems that you frame perfectly got hit, dashed, and healed. As far as I’m aware, a lot of glitches seem to happen when you get hit and preform an action at the same time, I think that may have happened here. I’d say you should try to keep preforming this glitch so we can have more info on how it works. I’m not a mod, but I’m just trying to give you some advice.

Ok, I looked at this in full screen, it shows you got hit, parried, dashed, and healed right after eachother, that might be what happened.

Posible Speedrun move?

I mean, in all fairness, you could technically play the game normally, and then do a death run before the final boss where you kill every enemy without bench heals since that resets the enemies too.
