Once a reaction is tapped on, it is gone to the wild forever. There won't be any undo. With 'Like' button there is no chance of accident as there is nothing else. And considering the reaction feature is being built for mobile - small screen, distracted attention, unsteady hands, the chances of 'oops' scenario are quite high.
