You have defined \Set as a command that takes one mandatory argument 
and one optional argument. Your definition of \INMSet passes to \Set 
only the mandatory argument. You are therefore executing the equivalent 
of
    $\Set[\empty]{\Mname{M}}{S}^{\text{in}}$\xspace
where the {S} is simply typeset alone and is not the argument of 
any command.
