Then why does it have intense sharp lines pushing AWAY from jozu's elbow strike, that is on aokiji's lower body? That's almost always used as an impact situation. Also that's not how "that represents aokiji's midscetion breaking", aokiji isn't flying off with the impact lines, it was hit by jozu's elbow, which had the impact lines.
Also on a basic level, look how much jozu followed through, he's WAY past the point aokiji was at, he's pretty much where aokiji was himself and he's still crushing through.
