Kiss wary of wounded Leinster
Paddy Jackson spearheaded victory that day with 18 points that went a long way to ensuring Ulster finished the regular Pro12 season in fourth place for a third successive season.
A repeat outcome will ensure their place at Murrayfield for the Pro12 Final at the end of the month against either Connacht or Glasgow Warriors.
But Kiss is taking nothing for granted.
"It was a good win, without a doubt," Kiss told the Irish Times.
"But I've got to say that Leinster were probably a little bit underdone.
"They had some guys that hadn't played a lot of footy.
"We're likely to expect a lot more of the tactical kicking game.
"They will not be the same team we played here, and I don't just mean the personnel.
"I mean the type of game they'll play.
"I'm wary, they are a very good attacking team.
"Without a doubt, the set-piece battle will be important.
"I wouldn't say it's an area that I'm worried about, but it'll be key, at times.
"If it's not quite right, we like to think we can play away from it pretty well."
