It's purely cosmetic and hinders readability. Extreme cases like shortening variable names to a single letter may run afoul of Blizzard's addon policy due to their obfuscation rule. You can only really get away with it when writing for macros where the size constraint is an issue. There are other size optimizations I used in the code I posted like parenthesis are optional when the only argument to calling a function is a literal string or table constructor. For the most part, it's best to stick to a more normalized style when writing addons.
