After you scan the code, the verification app asks you "do you want to verify for example.com?"

The camera isn't the part doing that verification. The google service serving that "reCAPTCHA" is what's doing that validation. Unless you're using a custom browser that is reporting a different domain to google than the one requesting the reCAPTCHA, google's service will know which domain is which.
