The difference is in a scatternet, each move between piconets had to create a new connection (1. master1 -> slave, 2. slave -> master2) The new mesh standard, I believe, is a flood mesh. There is no new connections required because all messages are broadcast on the advertising channels and each node rebroadcasts when it receives it. (with some log of previously rebroadcast messages to avoid infinite loops)
