Only sometimes. If I remember correctly it depends on the size of the character and the angle at which you hit 236B. It's hard to test properly because sometimes, hitting 236B at an angle makes 66B whiff. I've gotten it to work somewhat consistently on Zas after stepping once to the side, and it does about 78 dmg. This is about 10 dmg more than the staple combos.
The other weird thing about this angle, is that the camera tends to randomly switch sides after 66B, making it really hard to judge if you can even get the IWC to work right.
What I can say though, is that if you land 22B from behind on certain sized characters you get AS B and then BT A+B combo for 89-90 dmg. That's Talim's most damaging NH combo so far. I know it works on Astaroth, Rock, Siegfried, and Nightmare so far. Haven't tested Zas and Liz yet. (Yes, I know it's not likely to happen in a real match, but it's something to consider if you manage to step around something.)
Edit: Liz is inconsistent, but it works. Zas it doesn't work at all. Sieg and NM have camera altering issues with this.
