Yes, that's right. I guess that what I'm trying to understand is more along the lines of why is it bad for your code to have a variable set as undefined? (ie, what sorts of problems does it cause?) and how does setting it to null instead fix or improve it?

I don't think using null will fix or improve anything, it's just a good practice to follow.
