白勇例句,怎么理解同位语

maxiv

Like many others of his generation of Native American leaders, Joseph Brant lived in two worlds; born into an Iroquois community and Instructed in traditional Iroquois ways, he also received an education from English-speaking teachers.

B. Like many another of his generation of Native American leaders, living in two worlds, Joseph Brant was
C. Like many another of his generation of Native American leaders, Joseph Brant, living in two worlds,  was
...

解释说以上两个选项是错误的
原因是BC选项, Like sb., JB was born into ... and instructed in ...(句子1), he also received ... (句子2).
"句子1, 句子2永远错"
----------------------------------------------------------------------------------------

疑问如下
... leaders, living in two worlds, Joseph Brant ...
... leaders, Joseph Brant, living in two worlds,  was ...

两个句子中的这几个逗号就是合理连接吗?
为什么不需要连词呢,难道是同位语?

maxiv

怎么没人理的...

living in two worlds是插入成分，表附加说明，连同前后的逗号去掉后应不影响句子结构。

B选项在我看来有不止一个问题，like从句后面应紧跟逻辑主语，不能有插入成分的。另外一个问题就是这个living in two worlds既可以修饰the others，也可以修饰Joseph Brant，因此对句子的理解会产生歧义。

也就是说我应该再看看“插入语”的概念是吧，谢谢！
