Yes, \definesymbol[a][b] is roughly equal to \def\a{b}, for example
\starttext
\def\something{aa}
\definesymbol[aa][\something]
\symbol[aa]
\def\something{bb}
\symbol[aa]
\stoptext
This is what is also happening in your case. You need to go back to the
definebuffer and processbuffer as suggested in metafun manual.
I do not know if it makes sense to have a \edef version of
definesymbol. In any case, getting expansion to work with \getMPdrawing
is going to be difficult.
