The neutral is rated at one size smaller than the power carrying conductor.
So, if the two 110 outlets are rated to carry power equal to what the
neutral is rated than this configuration will work (30 amp neutral rating on
12/3 basically rating the outlets at 15 amps each). I am surprised that the
inspector allowed this on an industry outlet such as a woodshop that
normally requires a full 20 amps per outlet. I use this configuration all
the time when wiring houses. The bedroom circuits are under rated because
they may carry a clock, TV, or a lamp... normally all low power items.
Pulling a three wire saves money because the bedrooms are normally the
furthest from the panel.
