I've already explained why it helps, and I'm not lying when I say it does help. Perl is the language of AND rather than OR, and there is more than one way to do it, so I personally don't value categorical imperatives about best practices too highly.

(Also, perl -w warns you if you only use a variable once, so I don't think your example is valid. Of course, if you misspell it the same way twice, then you have problems.)
