Updated means renewed? I do not think so.
Well, maybe I focused on the wrong thing when I read
"Expiration Date: 22-may-2015", I just assumed that the update of the DNS record with this info meant that the domain had been renewed for another year.
I understand now that this is a temporary year given by the registry in order to allow the domain name to still remain registered even though the domain has expired, pending payment. Silly me!
