Results from elsewhere in the division could help determine whether or not that semi-final is played at the Kingspan Stadium.
Should Kiss's men suffer defeat, however, they will require other matches to fall in their favour.
But rather than get bogged down in such permutations, Kiss is determined his players do not take their eye off the ball.
"Our focus is get the four points and, if we do that, it's mission accomplished," Kiss told the Belfast Telegraph.
"We're still in the hunt and it's a really tight, tough competition. To be able to get a win this weekend would be special but we know it won't be easy.
"We're at home, that makes a big difference in this league, but against Leinster nothing is guaranteed unfortunately.
"For us to get a home semi we'd need a couple of teams to drop something this week.
"If we win this weekend and a certain result goes our way then we probably can't be knocked out of the top four.
"The picture changes and throws up another story line. If we get the win, we're in a really strong place.
"For Leinster, even if they get a losing bonus they'll feel they're in a good place but a win for them puts them absolutely in the box seat, so we know they'll be desperate."
