More than highlighting philosophical viewpoints and problems, though, I think it highlights the problem with hypothetical situations. It wants to apply basic/static/general beliefs to these unlikely hypothetical situations.
--It asks you if it's always wrong to kill someone.
--So you might say yes.
--Then it asks if you should do nothing and let a train kill four people...or do something, switching tracks and only killing one person.
--So since you want the least number of people to die, you do something so only one dies.
--Then the site tells you this isn't in line with your answer that it's always wrong to kill. Cause you did something! Ha! Gotcha!
This isn't an "ooo, clever, I hadn't thought of that!" thing...it's just showing the problem with unlikely hypotheticals, and doesn't allow room for case-by-case judgment.
