I agree I'm speculating, but I just don't think this theory should be scrapped only because one old comment.

What reason would Monty have to spoil this fact at that time?

If you notice he is debunking the theory speculating Yang is in fact Summer Rose. So basically he is saying: "Summer Rose is Ruby's mother. That means Yang is not Summer Rose as she (Yang) is Ruby's sister." (as I understand the all we knew about Summer Rose's identity at that time was the name on the gravestone).

If he used "step-" at that moment he would spoil a plot point... while talking about different theory that about something else entirely.
