Yes, the articles do a lot to demystify things.

But the article and link to the mag is also excellent, such very similar inspiration is perhaps directly where ADA/Amano came from, it's not that impossible to see and figure out now is it?
Amano suggest this and shows such examples.

The same types of layouts just done in a tank.

"Nature aquarium" might not be the best descriptor, although such gardens and methods are all ultimately derived from nature, the idea and layouts are pretty well established long before "aquascaping" evolved. We have just taken that and worked it into the hobby.

Now, the same can be said about Dutch scaping as well.
