Double-clicking workflows that appear in the *My Workflows* folder in the Automator Library opens the document; but double-clicked applications are launched, rather than opened (a bug report has been submitted). A workaround for this is to drag the application into the workflow pane of an empty Automator document. The workflow will appear, ready for editing. This works for .workflow files as well, of course.
That’s not a bug: I think you missed the point of applications: When you double click on any other application, it EXECUTES. Applications are sometimes (on that other platform, anyway) referred to as “executables”. The point of saving it as an application is that it acts like an application rather than as a document. If you opened it in Automator then it would be being treated as a document, not as an app.
