This all HW and fixed-point, and a very particular situation.
The mixer described here would be used typically for setting up
a number of monitor mixes. Some signals could end up at a low
level in a full mix, and at full level in a channel used to
monitor just one instrument. It would be perfectly possible
to arrange this without any additional internal headroom, but
that would require a lot of attention from the user.
Having intermediate signals at higher fixed point resolution
means that you have more room to e.g. compensate for too high
gain on all input channels by reducing group gain, etc.
 
So two points seem to be important:

- this is all about usability, not quality,
- it would not be required when using floating point.
