Because rising demand was the reason prices rose in the first place. Assuming normal demand and supply curves, the quantity of oil demanded is now lower than what it would be at the old price, but higher than it was at the old level of demand -- which is consistent with what we observe. To see why the expectation is reasonable, you can draw a
supply and demand diagram for the oil market. The demand curve (quantity demanded as a function of price) will slope downward -- the more expensive oil is, the less consumers will buy. The supply curve slopes downward -- the more expensive oil is, the more producers will supply. The point where the curves intersect represents your price at market equilibrium. Now, consider an unexpected increase of demand from India and China: At any price, the quantity demanded is higher, shifting the demand curve to the right. At the new equilibrium, the price is higher. The quantity supplied and demanded is also higher; but because of the upward sloping supply curve, this extra quantity is smaller than the ofiginal shift of the supply curves.
All of this is much harder to explain in words than on a drawing board, but I hope I have made the point reasonably clear.
