I never understood this logic.

The material on both sides of the mask are the same, no? A mask can prevent a virus from leaving your nose/mouth but not enter?

It is not logic, it is science. The mask prevents droplets from your lungs from dispersing throughout the air. It is not as good at sealing your respiratory system from droplets in the air.
