Because blinking is not controlled in the brain hemisphere. Voluntary motor skills originate in opposite motor cortex, but blinking is not voluntary but more a reflex, or automatic motricity. This kind of motricity (which represents 99% of human motricity) is governed by the basal nuclei, which does not respond to the "opposite" logic.
