At B, if tails comes up (p=0.5) there are no blues—if heads comes up (p=0.5) there are no reds. So, depending only on the coin, with equal probability you will be red or blue.
It’s not unreasonable that the probability should change—since it initially depended on the number of people who were created, it should later depend on the number of people who were destroyed.
