It's of course the right way to post any bugs, even regarding the documentation, on the English forum.
And I can say you why: the German and French docs usually are 1:1 translations from the English docs. Mesa (for the French docs) and I try to avoid any translation errors. Almost all missing or 'better to be described' things affect the English docs too. So most of the time the English docs will be improved, and then the German and French docs too. And often there is needed some internal knowledge too, that's why the English forum (with participation of Fred) is the right place.
Specific to this topic: it will be checked (even for the other languages, especially the 'English source docs') and improved. So thanks for the report!
