There is a comment just below (line 39) that explains it. Maybe adding an explicit "so no need to call super.dispose()" to the comment would be helpful.

It looks like it's probably OK, but only because the superclass method has the same check that this one does. If you care relying on that, you will want to document that assumption, although it might be cleaner to just call `super.dispose()` unconditionally.
