This is kinda like back when people said Zoro used Haki back on Shabondy, when the bounty hunters can up to him. Clearly it wasn't, as no one fainted. From all the cases of CoC being used, we see people/animal fainting with crazed looks on their face (squirly eyes or foam from mouth). These guys just fell back on their backs in fear. We are both making assumptions, so it's time we considered from both sides views.
