Yes. More specifically, when region is active, `fill-paragraph'
completely ignores `fill-paragraph-function' and directly calls
`fill-region' -> `fill-region-as-paragraph'. This behavior cannot be
customized by major modes, so Org has to override the whole
`fill-paragraph' to perform syntax-aware filling.
