Obviously he would figure out it was a lie when he was released from their captivity, which no doubt only fueled his anger towards the Thalmor. But he was captured before the fall of the Imperial City and was tortured for information. During that the city was besieged and captured by the Dominion. Ulfric then finally cracked under the torture and they told him that the information he gave them was instrumental to the fall of the city.

BTWm what you are suggesting is just stupid. Why would the Thalmor make dossiers, some with obviously correct information and others with supposed false information (according to you), and keep them in their torture chamber just in the off chance that someone would sneak their way in there and find them. That just sounds idiotic.
