I'm no expert on enfuse, but 16 bit images do not contain the same amount of information as two 8-bit images. There's at most about 10 bits (stops) of real information in that 16 bit file, see also http://theory.uchicago.edu/~ejm/pix/20d/tests/noise/index.html. If you are talking about 6 8-bit images created out of the same 3 16-bit images that does sound unexpected (again, knowing very little about enfuse), but if this is 6 exposures vs 3 I'm not surprised.
