It's not about knowing the core differences, it's that the actual practice of writing a lot of C makes one familiar with its advantages. It's difficult to appreciate the value of C's small size if you are only coding in C++. Without doing a lot of coding in straight C, it'll be a lot harder to understand and recognize the various tricks and techniques other C programmers use to make the most of the small language. I'm not saying there are no good reasons to learn C++. Just don't think that you'll really appreciate C until you've actually used it all by itself (with maybe a few C++isms here and there like //comments).
