@cartofy I don't know what your "area of interest" is (and honestly, don't care). But if you paid a slight attention to only a few changes that have been included in this changeset, you would see these were country-level changes (indeed, to the name:* tags on them). This would give you a hint why the very simplistic "draw a simple box" area-of-changeset approach chosen by OSM developers (as opposed to any number of more informative and meaningful approaches to showing what's changed) produced what it produced. But indeed, if throwing off-the-cuff questions/comments at other editors demanding explanations in this form is your cup of tea, this will simply get you ignored next time. As you can see above, I've been nice to you and answered your question first before hinting at you to avoid disrespectful comments. You clearly didn't get the hint ;)
