It says, same personality's good enough,

应该说人格同一可以确定同一个人
as long as there's no branching.

只要人格没有被划分到其他人身上
If there is branching,

如果人格出现了分支
neither of the branches is me.

那么每一条分支所在者都不是我
Now, if we say that,

现在如果我们这么说
if we throw in the no branching clause,

加入无分支这一限制条件
then we're able to say, look,

那我们也可以说
in the original story I was telling,

在我刚开始讲的故事里
where there was the Michigan guy

如果有一个密歇根人有着拿破仑的人格
who had Napoleon's personality but no New York guy,

同时并不存在那个纽约人
that really would be Napoleon,

那这个密歇根人就会是拿破仑
because it would have the same personality with no competitor.

因为只有他一个人拥有拿破仑的人格
