I'd understand it as a preference if it in fact did something useful for your application here. But it does nothing. It's like throwing "/o" on the end of a regular expression that contains no variables. It's pointless.

That's why I wondered why you did it. You're doing nothing. It'd be like having an extra variable declared, and initializing it, only to never use it again in your program. You're going to extra work to do something that does nothign.
