Yes, but that's only when the origin changed compared to when you added it to the password manager. Same thing for Passkeys, won't work if the origin is different, so you double-check that the domain in your browser address bar is the correct one.
Obviously normally you don't do anything except click on the account that shows up, since the domain matches.
