Seems to work indeed
Somehow I have to hit C-cC-n to get fontification inclusive of subscripts getting lowered
to work after adding  a $ at the end of \newcommand\foo{$}%

% -*- mode: latex; -*-
%
\def\foo_with_underscore{}
\newcommand\foo{$}%
% a comment
A foo_bar^bar{$}
% a comment
B foo_bar^bar{$}
% a comment
C foo_bar^bar
$
%
%

but all looks fine to me. Thanks!
