Since it is targeting pdftex and xetex engines, it makes , an active char in mathmode and redefines it as a macro that uses look ahead to check if the next token is a digit. In principle a cleaner implementation is possible in luatex (without using active characters), but I am not completely sure about this. It will be better to handle this as part of \mnum macro.
