The support is in two places (I'm guessing). !. looks at its u and v and sees if they match one of the supported forms; if so, it makes a mark to tell the u verb what the fill was. The support is in both places, I would guess.
You are right in general that (u conj v) might just vector off to special code, but I'd be surprised if ;!.f did that.
