Do not use a pronoun to refer to an implied antecedent
Make pronoun references clear
Grammar

A pronoun should refer to a specific antecedent, not to a word that is implied but not present in the sentence.

Modifiers, such as possessives, cannot serve as antecedents. A modifier may strongly imply the noun that a pronoun might logically refer to, but it is not itself that noun.
