Probably, since the file name is generated based on some hash function 
of the code snippet, so both snippets get the same file name. How likely 
is this to happen in a practical document? Well, perhaps it is, since it 
could be some short example just showing a clef or a C major scale or 
whatever, that appears several times in a document.
