I think that what Monty comfirmed was that Ruby and Adam weren't related. Nothing about Adam and Yang.

And he also confirmed that Cinder was not Ruby, Blake or Yang's mother.

At least that's what's in the wiki.

Personally, I wouldn't mind if they really are related, I just hope that Raven was Adam's teacher.
