When I saw your code I didn't understand why the last example was so
complicated. Then I tried to simply write:
\score { {a4( b c' a \makePercent s1 <>) } \layout {} \midi{} }
and discovered that lilypond stop the slur before the percent!
So thank you for your code!
Ciao, g.
P.S. Yes, the midi output of your examples are all the same. They are not
the same if I use \articulate script because in that case
a( b c' a) a( b c' a)
generate a different output than
a( b c' a a b c' a)
