If a characters pierce is reduced to zero pierce would it still be considered pierce? More specifically, since the opposing character is attacking with pierce, but its reduced to zero, would Jazzs ability trigger, allowing only two damage to hit?

A character with Pierce, whose Pierce score is reduced to 0 or less still has Pierce.
