This is true, the tongue involvement in taste is very limited. When smoking the only part of the flavor your tongue is perceiving is the sweetness or sourness of the flavor. Everything else is from smoke that goes up the pack of your throat and into your nasal passages. I'd suspect that with the narrower gauge of the hose, the flow rate is decreased (obviously). This means it takes longer for you to fill you lungs. This increase in fill rate means the smoke has more time to travel up into you nasal passages, allowing you to better "taste" the flavor of the tobacco.
