Gareth McAuley scored West Brom's first goal of the Premier League season in stoppage time to cancel out Steve Sidwell's strike and extend Fulham's winless streak at Craven Cottage to six games, since the April 1 defeat of QPR.
The draw prompted a vocal minority of Fulham fans to call for Jol to be relieved of his duties at the final whistle.
"If we would have been bottom of the league I would have understood it," Jol said.
"But we are 12th in the league now ad we were a bit unfortunate.
"We should have had six points, so that is a bit disappointing that people boo.
"I always say to the players as well, it is very hard to fight expectations and expectations can make you very unhappy.
"It is the same with women as well. If you expect too much of them, you could wake up in the morning with a big shock.
"If you don't expect a lot of things... I think we are 12th in the league so for me it is not a big problem.
"It is a bit disappointing that there are people that probably think we should be (doing a lot better)."
Jol was happy with the performance of his side, bar the late lapse in concentration which led to the Baggies levelling matters.
"If you soak up pressure in the last 10, 15 minutes, it is always possible to concede a goal," Jol added.
"It is always the same in football. If you score one goal and they smell blood, you have to score another one.
"I haven't experienced three offside goals in one match before, especially the one from Berbatov. I thought that probably was not offside.
"The third one with Bryan Ruiz, he should have scored. He was six or seven yards out and he hit the bar."
Ruiz will undergo a scan to determine the extent of his injury while Berbatov went off with a hamstring problem.
If it felt like a defeat for Fulham and Jol, West Brom boss Steve Clarke was content.
McAuley has now scored in three successive games after twice netting for Northern Ireland on international duty.
"He's had a good goalscoring run and for us a really important goal," Clarke said.
"I thought we played well. Certainly better than our last performance at home (a 2-0 loss to Swansea).
"I thought second half we were good, we played good football. We created some really good chances that on another day, when your confidence is a bit higher, become goals.
"The belief of the players, the character of the players to keep chasing the game and to get the goal in injury time was great.
"It shows you the character of the group of players I've got."
Victor Anichebe and Morgan Amalfitano made their Baggies debuts and showed some potential, but another deadline day arrival was absent.
Clarke hopes issues over Stephane Sessegnon's paperwork can be resolved in time for next week's clash with Sunderland.
"When you transfer from one club to another you have to reapply for your work permit," added the Albion boss, who is optimistic Shane Long's knee injury is not too serious.
"There was a little glitch in the process yesterday that delayed it and unfortunately for us he wasn't available.
"Hopefully it will be resolved over the weekend, or Monday at the latest, and he'll be available to face his old club next Saturday."
