The joke is that trolley problems are usually used to portray moral dilemmas, so the teleporter is a subversion by rendering the trolley question irrelevant.
The trolley is still relevant because if you don’t step into the transporter, people die. If you do, there’s a good chance some version of you dies, but some version of you survives. So is the current version of you more valuable than the lives of the people on the track?
