I don’t think it does… it says

countryName is not in the list of things you can’t include, and it says not, so although countryName is ‘Subject Identity Information’ it is allowed in DV certificates if verified using  This makes sense because in the other cases you’re determining the countryName from the domain name or IP address.

In olden times some CAs would put countryName in all their DV certificates.  I suspect that was working around some other bug!
