How can the same grain line be on both sides of the bridge? Well somethimes the bridge is "tilted" so that the pressure of the strings from down pressure and pulling through swagger pulls the bridge forward. (Or so I have heard) That tension might cause a crack to appear on both sides of the bridge. Ever seen a wave in the soundboard on one side of the bridge or another?
