It was a light-hearted comment. When I first started using MVS - coming from a quasi-competitor - putting DD cards after the EXEC card came across to me as bizarre. On the other box, we allocated the files needed then ran the program using the allocated files. If you look at the JCL sequentially (like reading a book or something) the stuff on line 1 should happen before line 2 etc. Thus, logically, the DD cards should appear in the JCL before the EXEC card. Back then I didn't understand about converter/interpreters, initiators, and all that stuff.
Before I ran on OS/360, I worked on DOS. It struck me as confusing to have control cards prior to the program name.
The book may be a bad analogy - would you really expect the glossary and index ahead of the text? I think of it more like a meeting agenda: summary information on top, followed by the individual items to be considered.
