I don't see why this is so complicated, the short answer is ''Yes'', if this was a game Enma clearly would have +X number stat, Zoro just claimed last chapter he isn't making full use of it yet instead of talking about his 3 swords as a whole so clearly he can pull off greater feats with it and this has been the case for ALL of the new swords Zoro has picked up in the series, people just seem to forget about it and single out Enma.
