No, it's how one very specific community of experts understands it. It is not some kind of universal law of definition that it must mean that always and everywhere. As far as what is confusing, that is a matter of perspective. I think it is confusing (to put it mildly) that the C community has chosen to use "undefined behavior" to mean "it must never happen, and anything goes if it does". That is extremely counterintuitive, and only makes sense to those who live and breathe that world. So if the standard is to be "avoiding confusion", then we better change the definition used by the C community ASAP.
