Same thing. It probably became a Harumafuji non- henka when he started doing it more, but it is called a henka non-henka for the benefit of foreign fans who don't see the difference. We blessed few are here to guide them. As I watch all bouts from March 2015 lately for some reason, it seems every other Harumafuji bout was an HNH. I also don't see why any Harumafuji fanboy should be offended by this. It's a good technique that with time has grown apart from a henka per se and usually ends as an uwatenage, as opposed to a henka which usually ends with hatakikomi or hikiotoshi or loud sighs from the crowd or shouts of "FOUL!! NOT FAIR!" by the FNF (Fanboys not Fanboys).
