No, you don't rely on this use-case. You rely on the same work-around.

If both mixers should be handled as one, then it should be PulseAudio or
ALSA making that connection between the mixer tracks.

File a bug against PulseAudio with the output of "amixer -c0", the names
of the tracks that should be handled together, and the name of your
sound driver. I'm pretty sure this can be fixed without resorting to a
work-around.
