Your mini site is essentially correct, it has to do with the surface tension of the toughened glass. Because the glass is baked again after cutting and shaping the surface shrinks thus compressing the internal structure of the glass and hardening it. When you clay bar it you essentially are polishing the surface at a molecular level creating an uneven hardened surface. The compressed glass under the hard surface coat just needs the smallest weakness in the surface tension to cause it to fail and all it would need would be something as insignificant as a sudden temperature change or even a decent bug splatter at 100kph to "pop" the windscreen.
