Given Ruby's surname is Rose, we can speculate Summer never married anyone - be it Taiyang or Qrow.

Yang's surname is Xiao Long so we can speculate Taiyang and Raven were/are either married or in a relationship that would allow Raven to register Yang under the different surname than her own =  that of fathers.

That would not remove the possibility of Tainyang ACCEPTING the fatherhood of Ruby (for whatever reason that would be between him, Summer and possibly Qrow), even if biologically he was not her father. If you accept the parenthood, the biology doesn't matter =  the child is considered yours. And in that case Ruby and Yang would be legaly half-sisters...

This way Monty wouln't have lied... he would just not say the whole story. He could do it intentionally to create a red herring in fact...:/
