You don't HAVE to, but it is nice to always be ABLE to. Being able to write a registration system on your own can help you in a multitude of different ways. In this case, it can help him understand the use of MySQL (in this case in an outdated and insecure way, but still), arrays, custom functions, variable manipulation, etc.

Lets also say he wanted to write similar security code for another system, which he wouldn't be able to necessarily copy and paste from the system he was using yet had no idea how it worked in the first place. He would be helpless and would need to learn how to write such code later on anyway.

Maybe he's not even writing it to learn necessarily how to do this, but how the system works. I'm sure you as a professional programmer (at least that is what I've been told and can conclude from your work and blog) understand how important it is to understand the code that you use that others have written.
