Greetings Bahula,
I was able to meet and chat with Jorg about over a week ago. He definitely would like his article to reach as many people as possible and I’m sure he would have no problems / issues with you translating the article. But he did mention that he hasn’t published his article online or to the public yet because there was something that he would like to do first with the article before doing so, which I can’t exactly remember what the thing was.
Like Lal mentioned, I also don’t think he will have any objections with you or anyone translating the article, in fact he’ll probably be very happy to hear what you mentioned. But I would recommend you not to post your translation of the article online or to the public yet until you talk further with Jorg. In the meantime you can start working on the translation and I’m sure there would be no issues with you posting your translated work online or to the public at a later time.
I also posted in the Whatsapp group (with Jorg in it) about your message, I’m sure he’ll get back to you when he notices or see’s your message and when he has the opportunity to reply.
