Yes but they may not be checking the destination on the boarding pass, could just be checking the validity. We've had multiple cases of people transiting HK to China who ended testing positive, that means even more cases probably have made it through who didn't test positive since the positivity rate of inbound passengers is less than 1%.
The proposed segregation might finally put an end to these transits.
