So it IS going into cylinders? But how? Only way I see it possible is if next cylinder is binding the head and then blowing into neighboring cylinder through water passages...
If firing cylinder is lifting the head, coolant can't get in at this moment because of huge pressure in the cylinder :S

I'll bet what you posted here is how it happens. head is lifted slightly, and coolant goes to the cyl that is not on power stroke
