No the concepts are not distinct. They just look different. There's
this fellow from the planet Krypton (or wherever it is) and sometimes
he wears glasses and looks like a bit of a nerd, and sometimes he
wears his underpants over his trousers and leaps tall buildings at a
single bound. The latter dress and behaviour are usually associated
with the activity of crime-fighting.

It looks to me just like the case of {I}/{me}: there's this word ME,
which is pronounced sometimes /mi:/ and sometimes /ai/. The latter
pronunciation is associated with the syntactic role subject (at least
in my English, I know other people's grammars are more complicated).
