User blog comment:Raptor of Love/Aokiji vs Akainu and the Aftermath/@comment-5386071-20121203061508/@comment-8298508-20130417051221

X-Raptor, I know is a weird thing that admiral can stop whitebeard attack by positioning his hands. But no Haki user so far is able to use like haki aura protection with that style. Even shanks, rayleigh or luffy (z movie).

So I believe that is the same case like when aokiji protect girl from explosion at Z movie
