The transaction is generated locally on each node, so in theory, it would be generated with different server ids. But I guess it doesn't matter if the transaction isn't binlogged so the point is moot unless you are using Galera.

Ah, Galera, I see, thanks for the explanation. Yes, in MariaDB replication, GTIDs are generated as part of binlogging, so no GTIDs when sql_log_bin=0. I guess Galera is different. - Kristian.
