Thats not the point of the topic. This among other things can make a difference in calorie intake specially if you are trying to lean out.
For you 160 calories might not make a difference(it's only 160 calories extra that day so NO ONE SHOULD EVEN CARE) but 160 calories over a month of "cutting" equals to 4960 calories that could of other wise be avoided. Specially if we are talking about a spice not vegetables or fruits.
Okay but then where does the energy go IF you are not counting the fiber which indeed is part of the CARBS on the nutritional label?. If it really is converted to fat the calories would be counted as fat calories and not carbs which means the calories on the nutrional label are still counted towards the daily energy intake JUST NOT AS CARBS.
You're making the mistake of assuming our FDA makes any sense.
Because fiber is chemically/structurally a carbohydrate it is listed on the nutrition label as a carbohydrate. The fact that it has calories at all is what makes it necessary to include fiber on the nutrition label.
Think about if you were making alcohol. You would start with a sugar (carb) but then the bacteria would break it down to alcohol (still has calories, but not a carb) and the process would be finished.
So even though it is absorbed as a fat, fiber itself is a carbohydrate and listed as such.
Cellulose is simply a long chain of glucose. Just because humans can't break it down dosen't mean other life forms are unable to do so. I'msure you're not interested in the exact chemical process, so here is a short article about it.

I know wikipedia isn't universally regarded as a valid source, but this page has some decent info in the first four subsections and it's easy to understand.
