If it will only write to this one replica, that would mean, there is no consistency at all... It´s writing synchronously because the strong consistency mode can´t be overridden for writes

"An account configured for strong consistency by default will still write and replicate data synchronously to every region in the account. When the SDK client instance or request overrides this with Session or weaker consistency, reads will be performed using a single replica." https://learn.microsoft.com/en-us/azure/cosmos-db/consistency-levels
