That image is stupid. Twice the kinetic energy of a punch from Accelerator's twig arm is still very little. So, it would not suffice to just blow away whatever object Accelerator was punching. Therefore, unless Accelerator applies additional vector voodoo upon that object, he's going to ram his fist into it and hurt himself.

I haven't cleaned my "recent" anime folder (the one I use before I organize pictures into other folders) since last year.
To my knowledge his reflection shit is a perfectly programmed thing that he does not control, which is also the reason why that retarded Stop-the-punch trick is supposed to work on him.
As far as reflection goes, yes. However, he's also able to easily use a steel girder as a weapon by kicking it. In one particular occasion he throws a building (or a chunk of it, depending on the media) at another building. He does that by hijacking Earth's rotation.
