A few possible reasons: some are marked "fixed" when the patch in 
another bug actually fixes them. Sometimes people don't click the 
"patch" box. Sometimes people upload their patch as a zip, and so can't 
- because currently things marked as patches are served as text/plain (I 
think.)

Not if the procedure of the developers involved means that the patch is 
not necessarily attached to the bug.

Because not every attachment is a patch.
