Try to understand my point than write so much bout it.
Ofcrs it's Zoro haki that Enma uses, but we saw how much of it can Zoro utlises in attacks on his own in DR. He realises the limits that he can't cut the golem from distance (like Mihawk).
And Enma allows the user to use major portion of his Haki in one slash allowing the attack to be much stronger it usually is.
That's also why Oden only managed to scar Kaidou with Enma, and not the other sword.

probably not. He has used much less haki with shusui, wado to cut pica, the cliff in punk hazard than he has with enma cutting the cliff. He has to bring it under his control.
I wouldnt assume that is why oden scarred kaido with enma and not ame no habakiri just yet.
