Note that you can write this as

rinforzamf =
#(make-dynamic-script
   #{ \markup \line { \left-align \normal-text \whiteout
                            \italic "rinforza"
                      \hspace #0
                      \whiteout \dynamic "mf" }
   #})

if you want to.  It then becomes more straightforward meddling with it,
though this is not really relevant here.

Ok, here is the deal: this is an override, which is something happening
at a single timestep to _everything_ in the current context.  If you
want to combine them, you rather want a tweak, which is something with
its effect confined to what you are tweaking.

rinforzleft = \tweak DynamicText #'self-alignment-X #-1 \rinforzmf

should do the trick.
