While that's terrible, I've never seen anything like it in the wild.

 He loves coming up with unrealistic code examples that no decent programmer
would ever write then points and says look how bad macros must be. Using that
approach you can easily come up with highly contorted code that no one can read
as the Obfuscated C contest proves.
 

And you do like totally ignoring the context. This was an example of how macros work compared with how functions work.
Functions return a value of some type; macros yield a bunch of lexical tokens.
