OS/Input Question

[DJ_Blactricity]

So I was going through SKD's analysis of fenrich vs yutta again while reproducing the stuff as I followed along, but I have a question about the OS used by yutta at the time in the following link:https://www.twitch.tv/superkawaiidesu/v/5988024?t=40m38s

I'm trying to break down the inputs for the OS, and find what options it covers. From watching I know he barrier blocked low a few frames, stepped forward to put fenrich in the corner, and reversed dp. After playing around in training I came up with 1AB621C, but I rarely get dp. A lot of the time I get 3C j.2C whiffs with jin in the corner or I get 2C and get hit by j.2C.

Are my inputs right and my timing off? Also, how could I use this to cover throw?
