re: How is this not a violation of EEOC/ADA laws about revealing personal medical information?

*The Company* is also not requiring employees to disclose their vaccination status. Given that vaccination choices, willingness to disclose vaccination status and desire to continue wearing a mask or socially distance even if fully vaccinated are personal decisions, employees are reminded to be respectful of their colleagues’ privacy and choices. However, in order to avoid wearing a mask, employees must voluntarily provide proof of their fully vaccinated status to Human Resources by presenting an authorized COVID-19 vaccination card.

Wouldn't an employee continuing to wear a mask be a good indicator of someone who has NOT gotten the vaccine under this policy, and therefore an inadvertent means of mandating that employees let other know they are unvaccinated?
