Looks like it supports alternative proof of employment. They don't require disclosing identity as long as they are convinced you work for these companies.
And you propose that how exactly? Every method they mention has identity attached to it in some way. They specifically want to be able to deduplicate submissions too, so I don't see what non-identifying options you're imagining they might accept either.
