I would guess that the further testing was a compression check? Because the major damage severe overheating can do is warp the heads, which would compromise the seal between the water and the oil circulating in the engine. That's a bad'un. So even if it passed the test ("at this time," yeah), keep a close eye on your temperature gauge. And when you check the oil, be alert to a greyish color or (umm, worse) a "foamy" appearance--that's water in the oil. DO NOT WANT.
Gotta love those older cars, especially the paid off older cars! I still have, and still love, and still occasionally drive the Miracle Mazda. Twenty four years old, come November....
