At first, it seems counter-intuitive that the debris seems to be flying in opposite direction of the incoming bullet

This picture shows what I explained on the previous. Here, the impact is justa bit higher and the shockwave propagates straight to the rear and causes a breakout similar to the impact in the front. One can see here the outer edge of the shcokwave causing the glass to break in an allmost straight line along this edge of the shockwave from the rear to the front in an angle of about 22 degrees downwards.
