It's the same thing. A brief explanation that assumes you know some term or have all the priors to deduce some meaning just creates a situation where we may have to apply the 10000 rule again. A thorough explanation on the other hand is more likely to help the reader be part of not only the 10k that get the commic today, but also the 10k that get some other fact (or several!) today.
Or to paraphrase the 10k alt text: saying "what idiot doesnt know the difference between kills and selectively kills" is so much more boring than telling them about it.
