@Daniel, HG. Thank you for your kind explanations. I start to see better. I had not caught the fact that the "a" could link with a "none" modifier.
I understand the logic. I don't like it much though. It is strange that nothing more natural could have been imagined, without ambiguity, to chain simple moves. You guys have been thinking on it for a long time, so I guess it is not so easy.
