It's not only you. I also, remember every single one of these confirmations from Monty. Mainly because of how people were accusing Monty about mixing facts for saying that Ruby and Yang are sisters, then, saying that the are not, then, saying that they're sisters again. But this is not true, I checked it to confirm it myself and there is no contradictions.

Ruby and Yang are half sisters, both have the same dad but not the same mom. Summer Rose is always mentioned as Ruby's mother and Yang is never included. That could also explain who was that woman Yang was looking for. It could be her mother.
