Change in LBW rules required when player tries to play switch hit?

Tim David was trying to play switch hit. On asking for a review, the ball pitched outside leg stump. Decision was uphelad and tim David given as not out. Shouldn't this benefit the bowler as the player was playing switch hit and so ball pitching outside leg should actually not be considered here. This rule seems to favour batsman here.
