...I dunno why he said that, but in general, the miserable C99
"standard" makes it easy to cover up ignorance by saying things are
undefined: it's a sort of Copenhagen interpretation of C but far less
intellectually responsible than the epistemology of quantum theory.

Undefined behaviour is to make it easy to write optimising compilers. On
some platforms an overflowing integer might automatically trigger an
excpetion which is hard to override. On another one it might be difficult to
detect overflow at all. By saying "the behaviour on overflow is undefined"
both the compilers can simply emit the code register a = register b +
register c, which is generally what the programmer wants when he write a = b
+ c;
