Errors happens.
They do happen. But I have to admit, when it's in big letters, that one should be correct.
To me it looks more like remote access to miners produced by them. You can register dual miner on that website and then you can remotly check and maintain miners in your location.
That is the way I'm reading it. Management of (your) miners, through the Cloud (or Could). The Help section reads that way too. That would be nice. I was never able to get that concept to work with my S5's.
