Native Japanese speakers please help me

Hi! I am learning Japanese by myself but I can’t figure out how the reference system in Japanese works. For example,can kare彼 refers to a person that comes after it? like in the following sentence ①「彼が足の怪我をしたので、王さんはタクシーで家に帰りました。」 Can 彼 refer to 王さん？ Is the coreference natural to native Japanese speakers? In sentence ②「会社が彼を首にした後]、JohnがBillと電話で話した。」, can 彼 refer to John?
