The 3^^^3 bit makes it qualitatively different from any real-world lose-lose hypothetical. Remember that lose-lose hypotheticals are something that people in power, e.g. politicians, have to decide every day.
People in power have to decide about actual cases, which are always about expected utility, and in which knock-on effects must be considered. Most trolley problems have more in common with the DSvT scenario than with real-world cases.
But sure, when you add things like 3^^^3 people to a hypothetical, all normal intuitions go out the window.
