Cooling water flow & hydro-locking

[TeenGee]

Does the water highlighted in blue cool the exhaust manifold and enter the head without mixing with exhaust gases?
Is the red highlighted water flow the only water that mixes with the exhaust gases and subsequently cools the remainder of the exhaust (water lock, resonator, exhaust valve, & associated hoses) and out through the exhaust valve?
If this is the case, the water lock would need to fill to the level of the exhaust valves before water could cause a hydro-lock.
Am I interpreting these schematics correctly?

I dont see anything highlighted in the schematic. Water and exhaust gasses only mix at the very end of the manifold near the rubber coupler. Before it enters the water box

I believe this is correct. Takes a bit of time to fill the exhaust with water before it overflows through the valves and into the cylinders.
