I think (and i’m probably dumb) it’s supposed to be he splits the timeline then in one he leads into doing the coinflip and if he gets it right he follows it, in the other he delays and doesn’t flip so if he gets it wrong he just never flipped and he flips later, but the might be wrong and make less sense
IT DOESNT MAKE SENSE that coils power was able to make a coin flip the same every single time. he can only use 2 universes theres a 50% chance it’s gonna be heads. in his 2 universes theres only a 25% chance that one of the two flips will be heads. he gets double luck but theres no reason why it wouldnt be tails in both universes yeah. that doesnt make sense
