Front. Middle. Then rear.
Any thoughts or observations or inputs?

The attacking flow is just pushing the liquid rearwards, as long as time-averaged rearwards boundary-layer flow remains attached.
After the flow separates, the random chaos of the turbulence creates the back-soiling.
Keep in mind that, the water is eight-hundred and thirty-three percent more dense than the air, and cannot 'dodge and dive' like the air it's entrained in.
