I must admit, I don't know what a BU full node does when it receives a conflicting TX. I would assume that BU allows conflicting unconfirmed TXs to exist together in the mempool. It is up to the developer to handle these situations. Unfortunately, the double spends never appear in my mempool. I can see them in blockchain.info as double spends but I haven't seen any double spend in my own mempool. I'm periodically polling it and checking the inputs of all fresh mempool entrants.
