Afraid of the answer.....

Nothing short of maddening.

Just for laughs I unplugged the connection that the mechanic put into the hose from the top of the oil cooler and started the car for a few seconds.

Needless to say, coolant was flowing everywhere and at a very high rate.
There's no way that hose is connected directly to the drain hose as it's just too high of a flow rate.

But, for the brief few seconds I did have it disconnected, I did not see anything coming out of the drain hose!

I reconnected the hose and then lightly sprayed everything down with water to get the coolant off of the car and engine. I then let it sit a bit and then started it up.

It started draining drops and a small amount of coolant again out of the hose.
I drove it around a bit and noticed that it was draining most of the drive.

I pulled it back into the garage and noticed that there was steam coming out of the drain hole and the side of the car. That was probably some of the water I used to lightly was off the coolant.

I then started it up two different times and nothing was dripping out of the drain!

I will also take some photos of the manifold after it cools down a bit.
