I have bought glass from Molta Bella in the past and can say that he is a nice guy to deal with. I am sure his misattributions are a mistake. He sold me two pieces as Carlo Moretti and over the last few months I have had my doubts about them being Carlo Moretti. The look of them appears to be Moretti but I haven't found anything like them with labels on it to confirm his attribution. Perhaps I will post the items and let you be the judge once I get my new camera.
