I've heard numerous people suggest that the engine "could" ignite on fogging oil. I have not been able to find a substantiating source for this concern. In my particular case I used Amsoil synthetic fogging oil which may have a higher flash point than others. Besides, what if the engine did start? I would also suggest pulling the stop and decompression levers. There is no need for compression and the extra fuel just thins out the fogging out.
