standing was used only for characters standing upright (no bent_over or leaning_forward), but I see Danielx21 changed the wiki.
Oh, sorry.
In my defense, IIRC, the tag standing really had some hundreds of posts with people bent over or leaning while standing, even before I edited the wiki.
Also, searches like bent_over sitting, bent_over standing and bent_over kneeling yeld different results - with someone bent over while sitting, or while kneeling, etc. There is some noticeable noise, though, when distinct people with different postures appear in the same image.
