Is this too much of a necro? Sorry in advance.

I can't help but feel that Ruby wouldn't know, largely on the basis that Yang seemed markedly hesitant revealing to Blake that she and Ruby were only half sisters. It could be chalked up to just emotional pain, but I think that hesistance is also indicative of her and Taiyang's having not informed old Rubles of the truth.
