I'm not sure I follow the distinction here, or at least why it would be important? i.e. if I parse "decide how to handle the error" as catching the exception, where I handle it is surely basically anywhere since I'm not restricted in calling into other code to do so.

Common Lisp exceptions are resumable which is the main difference between it and more common languages like Java and C++. e.g. "Decide" can also include deciding to retry the operation with different inputs.
