I did a 1400 mile trip on my leaky head gasket. And I was giving it some good throttle while far away from home... it was a dangerous game. Glad I made it back without major problems.. had a medium problem and had to fix a blown coolant fitting on the side of the road but yeah.

because the air bubble is purged, and coolant is now fully (or at least more so) enveloping all the metal and transferring heat properly.
until a significant amount of air is added to the system again. you give that thing 100% throttle for a bit and you can bet the coolant temp will spike, and might not come back down. the extra pressure in the system might blow off a hose or cause it to dump all out your coolant tank etc.
same exact behavior on my car.
