It does not happen with TeX using
 \catcode`\‘=\active
 \def‘#1’{\csname #1\endcsname}
sure, but when you do
\appendtoks
 \catcode`\‘=\active
 \def‘#1’{\csname #1\endcsname}
\to ...
only tokens get added to the register ... so the ‘ after the \def is not active (yet)
in addition when tex sees a $ it will look for a next token (in case it's a $ for display mode) and it sees a quote (no everymath doen then) which it will push back
OK. TeX does not parse the way I expected.
