The purpose of this law is salary transparency, not necessarily on salary equality across positions in the company. It makes it so that applicants can see what all employers are offering up front, which incentivizes the employers to be more competitive on salary offer if they want applicants to choose to apply there. Salary equality for equivalent positions within the company, as you're describing it, would require companies to publicly list what each of their existing employees are making, which is a completely different thing than what this law is requiring.
