Creos use different terms so they can maintain their (otherwise unsupported and provably false) claim that evolution has never been observed. Even the most ardent creo knows that they can't claim with a straight face that organisms never change. Thus, they exploit a purported distinction between micro and macro. However, I've never seen a creo explain the distinction without relying on their undefined and undefinable term "kind." Thus, as far as creos are concerned, the difference between micro and macro is as meaningless as the "kind" nonsense.

Re: this can be a useful distinction ...
but there are also different mechanisms at work, and this is where I've modified my opinion.
As I understand what you've said, the only difference in mechanisms is that the "tendency towards stasis" no longer operates once a population has divided. In other words, there are no additional or different mechanisms that operate at the "macro" evolutionary level, but simply one mechanism that is no longer operative. Is my understanding accurate?
