I guess what you're saying is that machine code is an "intermediate product" in the sense that the final product must include the compiler, and the machine code produced by a JIT compiler is useless by itself. And I agree with your overall point, JIT compilers and VMs shouldn't be in there. You might as well include all interpreters. If you look at a JIT compiler as a black box, it acts like an interpreter, and I'm pretty sure this is meant as a practical graph ("what can I do with this language") rather than one that describes the internals of compilers and interpreters.
