My local Haku player would do this. I think I beat him pretty clean with a dash 5c AA into air combo(or 623D to put him in the corner) most of the times he tried it.(i think he traded/ beat me if the j.2a was really close/low) I think 214D~B also scored me a clean counter hit as well.(not sure if i had time to charge for FC) With Hazamas back to the corner and/or meter that could end up with some big damage and corner oki.
Haku's j.C felt like it would stuff that or trade most of the time with proper distance. And j.D would beat it too obviously.
Also, we're both pretty scrub. So I wouldnt take this to heart.
