Depends on who else you expect to read your code after. I think it's safe to say that Zaxo knows that local variables automatically are set to undef. Which I assume is exactly why he noted it as such. I would hardly call it "junk". It works and causes 0 problems with the code. It's a stylistic decision.

I'll refrain from commenting on what I suspect you're wearing for undergarments.
