The whole process takes about 30 to 40 minutes and by that time with the car running it should be bled through. Pouring into the expansion tank may create bubbles I guess but those rise to the top as far as I am concerned.
Sorry, I don't quote follow the logic here. To make sure coolant was in the entire system? As in, you're checking for leaks? This doesn't seem like a particularly good way of checking for leaks.

You misunderstood me, I'm not saying bubbles are going to be introduced by running the car. It's going to be introduced by pouring antifreeze into the expansion tank. Sure, most of the bubbles will probably rise to the top, but it's not like the bleed procedure is hard to do or something, so why risk it? It's still best practice to bleed the system any time you touch the coolant system.
