Except by that logic, you could say that any user of a high-level language was really claiming (in the end) to be using assembly.
C++ once compiled to C, but even then people wouldn't claim they were using C, they'd claim they were using C++. "I don't use C++ because it's C with 'classes', I use C++ because it sets up my vtables and overloaded functions"
That analogy makes absolutely no sense. You are claiming an intended use. And then contradicting yourself by saying you don't use it for that intended use. The analogy would be "I don't use C++ to write programs, I use C++ to write words that have a particular syntax that a C++ compiler can understand and translate into executable machine code". And that statement is just as contradictory as the one you made.
