Yes, it's a BIG difference. Since the caller only knows about the file
it is passing as argument, it should expect that file can't be accessed.
However, an IOError for a different file (unrelated from caller's point
of view) is given.

Acutaly in this case, opening one file simply means opening two, so it
still makes sense. Now imagine another function was called there to log
something. Now having the errors in a same class stopped making any
sense.
