aside from the first heavy clip, all the other ones feel kinda unconvincing for yen to be cheating, or at least i dont really know how they seem like cheating clips.
for the clip at 2:17, where hes shooting at two soldiers i dont really think it looks that weird, he was initially shooting the soldier to the left that he already hit for some damage and then went forward a bit, but then that soldier jumped away and if he chased him he wouldve just been shot from behind by the other soldier.
and as for the flicking back and forth between the two soldiers, it was just one flick back to the soldier that jumped away that looks like he was just checking once again if that soldier was actually out of reach or not before committing onto the soldier closer to him.
id be interested in hearing other explanations for why the clips seem like cheats
