The possibility is there, not that low and the probability of who beating who isn't so clear-cut. FYI, WYH recently lost to Sun Yu in the CBSL and further back at the CNG more surprising losses, and we now what can happen to WYH sometimes. Besides, why wouldn't she want to earn even higher ranking points by entering the semis ?
The fact that CBA is sending Yao Xue to a SSP proves her potential. As for defending the MAS Open ranking points, she already succeeded just by being at the QF, anything more is a bonus. Moreover, with at least 5 other CHN WS ranked well ahead of her at 25, it's not going to help her much; she has to do much more than than that.
Just a friendly exchange of views, nothing personal; my post wasn't aimed at you anyway if you get my drift.
