I think the idea was that drowning Booker wouldn't get rid of all the Comstocks in the multiverse. For example, other Bookers may have been baptised a few days later. The point is that those baptised Bookers, even if they changed their names, wouldn't have become the extreme sky-racists that the first "set" would have become.
