The current directory is different for each buffer.  If you want the
script to do the right thing for the file /a/b/c/file, start the
script from the buffer which visits that file, not from the buffer
that visits /g/d/f/file1.

You are wrong: Emacs does _exactly_ what the user expects: all
operations from a buffer that visits a file assume the default
directory is the directory of that file.  This is not a global value,
each buffer has its own setting of the default directory.
