BB Rolled up on law like Harold in mist

Just rewatching clips from one piece, was rewatching Blackbeard encountering the Heart pirates. Anyone else notice after the recent revelations about Harold, that Blackbeards ship was just chilling in mist before they attacked Laws submarine. Blackbeard literally took a page put of Harold's book, it looks like his father's respect for Harold passed on because Blackbeard appears to be using the same method Harold used to attack ships.
