On corner posts the racking effect can better be transmitted by truely long braces ( ca. 2/3-3/4 post height) otherwise the post holds the load above the brace. Still it is a feature many ignore as a way to make a building more immune to racking.
That's why the German design uses long braces going down instead of cute little braces between post and tie beams that do little.
