That's because the definitions of $(2)_ASCIIDOC_CONF and $(2)_ASCIIDOC_BR_CONF
are common to all of that document, so we define them in ASCIIDOC, not
_INNER, or they'd be redefined every time _INNER is expanded.

OTOH, the $(2)_$(4)_ASCIIDOC_CONF and $(2)_$(4)_ASCIIDOC_BR_CONF are
different for each output type, so they only get defined in _INNER.

No impact on the behaviour, indeed, but no need to redefine the same
variable to the same value over-and-over again (well, just 5 times, but
still.)
