新手报道，求教OG SC52 关于逗号and前后主语的问题

yuha1111

To Josephine Baker, Paris was her home long before it
was fashionable to be an expatriate, and she remained
in France during the Second World War as a performer
and an intelligence agent for the Resistance.
(A) To Josephine Baker, Paris was her home long
before it was fashionable to be an expatriate,
(B) For Josephine Baker, long before it was
fashionable to be an expatriate, Paris was her
home,
(C) Josephine Baker made Paris her home long
before to be an expatriate was fashionable,
(D) Long before it was fashionable to be an
expatriate, Josephine Baker made Paris
her home,
(E) Long before it was fashionable being an
expatriate, Paris was home to Josephine Baker,

解释里说"，and"前后并列，主语应该一致，所以应该用人做前一句的主语。但是前后两句主语一致，不是把逗号去掉并且省掉后一句的主语更简洁么。前面有逗号的and完全可以主语不一致额，感觉og在扯淡，求解答。

也很有疑问！！and连接的两个句子主语一定要一样吗？
OG上是这样说的
This compound sentence (consisting of two independent clauses joined by the coordinating conjunction and) would be most clearly expressed if Josephine Baker were the subject of the first clause since she is the subject of the second clause: Josephine Baker made Paris her home would clearly parallel she remained in France.
