I think it's a fun literary style sometimes. Useful information doesn't have to be presented in some specific way to be useful, and in this case I think it's additive. I agree that it can be overdone, but it's pretty lightly sprinkled here. But it's the same as any other useful literary device, to answer your question. To make things more interesting or different.
