The lisp system always loads the installed maxima image, which, of
course, contains the code from the unpatched mactex. If a file is
changed, you have either to explicitly load it (like you did) or to
dump a new maxima image and to install it.
However, instead of changing mactex.lisp, you could put the code
snippet in share/maxima-init.lisp, which is automatically loaded.

Thanks for trying it out! Of course, I'll wait for comments by
mactex's author Richard Fateman or by other people who know this
package better than I do. In principle, we could easily add the code.
