The EU price is settled in a single daily mixed-integer quadratic solver run, so the prices directly affect each other when the solver runs. The goal is to reach a singular price across the system, theoretically, but like you say that becomes impossible due to transmission congestion. Either way: These low prices will be driving down prices across the continent, the algorithm will maximize export from these low-cost areas as much as it possibly can; that way the entire continent benefits from the windy weather over the baltic.
