I suppose it better than them getting it wrong, but sometimes you can notice these things only to realise that its just a particular crew or controller that regularly as a habbit of it.
I agree that too much "Chat" on the RT can be bad sometimes, leading to confusion or just pure frequency loading, however somtimes being that bit more human can help get the message across, or just create a more functional response. A plain Negative, can result in a non helpful response. Just like the comment about noticing someone saying "Confirm" how many other personality or voice traits do you often notice or comment on about a pilot or controller and form an opinion about?
