Yes!  See function try_to_bin in winsup/cygwin/syscalls.cc:
      /* Create unique filename.  Start with a dot, followed by "cyg"
         transposed into the Unicode low surrogate area (U+dc00) on file
         systems supporting Unicode (except Samba), followed by the inode
         number in hex, followed by a path hash in hex.  The combination
         allows to remove multiple hardlinks to the same file. */
