Decision in Activity Diagram with multiple Object Flows

Question

I tried to reduce my problem to the following simple example. If the profit is low and the customer is not a regular one then the order should become canceled. In all other cases (low/regular, high/*) the order is to be executed. How should I model the disconnected part in the middle? Wheter or not the client corresponding to order is a regular client follows from the data model:

I assume you are looking for the formally correct way to model this. Here it is:

If less formality is sufficient, you could skip the decision input flows and simply assume that the guards have access to any objects in the scope of the activity. Then one decision node is sufficient with a guard [profit=low AND not order.customer.regular Customer].
