In the TXY timeline: the Kaiou aren't really that concerned, since trying to use the style against them is sure suicide _anyway_, and the Kaiou heir - who was part of Katsu's genin team - seems to be pulling his strings _anyway_.
That aside, most of the Mist's soft taijutsu styles at their academy are deriviates of what the Kaiou came up with - the clan's concession to the Village.
Besides, Katsu's fights are usually very short, excessively violent, and witnesses aren't an issue.
I'm writing down snippets titled Hand, Claw, Fang as bits from his time as Genin, Chunin and Jounin respectively. They should be explanatory.
In the Replacement timeline: Katsu took some pains to not use any distinctive moves of the style during the Bell Test, since facing an adult Jounin in direct confrontation with taijutsu when in that body? Not the smartest idea.
He won't be going back to Saugai and Warugi type weapons anytime soon, since he needs to grow a bit to use them.
He picked up the gauntlet/chain weapon to compensate ... besides, after the Wave country mission? He could just blame his 'knowledge' of techniques on scrolls he'd looted from the Mist-nins.
For those of the Leaf who'd ask?
Katsu: Well, I _am_ a student of the Copy Ninja Kakashi. You wouldn't believe the things you can pick up from a sensei like that. *pulls out a volume of Icha Icha Paradise and starts reading*
Thereby redirecting interest at least a little bit. And irritating the Jounin, which ^_^.
