I don't see any evidence of him saying that on Twitter. He said Adam and Ruby are not related, while the tweets about Yang and Ruby that I note in my previous post do not argue against them being blood-related. He did say Weiss and Blake aren't sisters, and that Ruby's last name is not the same as Yang's, but we know all that.

See these tweets: 11:10 PM - 22 Mar 13, 9:25 AM - 18 Jun 13, 12:22 PM - 18 Jun 13

Had he said something to that effect then it was not on Twitter and I doubt he did say anything to that effect given his expressed reluctance to comment about it on Twitter.
