Previously Released Sales Orders going back on Credit Hold

We have a szenario that Sales Orders released from C1 credit hold are going back on C1 hold when starting Invoice print R42565. So no invoice in generated. Our thought is we are running R42950 in order to update the sales order exchange rate in Subsystem mode, so if changes occur in the Sales Order due to a changed Exchange rate, would another credit check run in the backgound and take the order back on C1 hold ?
