"absolutely choose" means that the other two players do not vote (since by rule the could only vote for each other - they can't vote for the third who has immunity, and they can't vote for themselves), so whoever they vote for goes home.
When it's 4 going to 3, the person with immunity has a tremendous amount of power and is usually the swing vote, but they don't have quite as much power, because it's possible for the vote to go 2-1-1 and therefore the person the immune player voted for goes to the end.
