This is mostly an intentional oversight on the matter, and players rarely if ever seem to care.

Also includes sheathing weapons to waist or other locations when there's seemingly nothing holding them there. Especially noticeable when the character is nude in that part of the body (e.g. bare upper body but weapons are sheathed on the back as if they had something there besides their skin to hold them there).
