Yeah, that's another one of those funny things: Native speakers are always held up as the gold standard, but sometimes an L2 speaker is actually better at writing for an international audience.

The first time an English-learner asked me what the rules were for position of adverbs in English, I had no idea what to say. I knew what sounded right to me, but I'd never tried to figure out why. But I can tell you the rules for German because I had to learn them myself.
