you would be correct however the butt part of tagging is whenever its visibly shown(as in we seeing it from the back side and not from someone upfront with their ass up)
the other cases for butt tagging is whenever the "backside" of the character is... quite large in size
along with other kinds of implications
doing something
having something
on something
something on it
or even colour if i'm not mistaken

Yeah, this tag just describes the pose, and not they physical aspects of the character. On e621 this tag doesn't imply any other tag as well https://e621.net/wiki_pages/904
