I'm not familiar with the "trustlines determine partition choice" feature of Stellar, but I am with trustlines in general; they are explicit app-level concepts that you define on your wallet, which in this case would say something like "I trust DB to redeem up to 1m worth of EUR credits".
If the Stellar client's behaviour in the face of a partition takes trustlines into account, that's much safer than the default behaviour in bitcoin, which I believe is "pick a partition at (pseudo)random".
It's possible to manually coax the client to pick a partition, but that requires user interaction, i.e. it's not fail-safe, it's fail-unsafe.
