Even if the last element in the end of an information flow is deleted, the information flow itself remain in the model. 
This behavior is different from when deleting elements in the ends of other relationships and is not intuitive for the user. 

Steps to reproduce the unexpected behavior:
1) Create two elements, for example classes, and add them to a diagram.
2) Draw an information flow and a dependency relationship between the two elements
3) Delete one of the elements, or both elements from the model
4) In the Model Explorer you will see that the dependency has been deleted, but the information flow remains.
