You need to look closer at the difference of your displayScheme results.
Your above definition is missing the element

    'origin (*location*)

in the make-music function arguments.  A music function automatically
tacks them onto the top music expression but not on everything below.
Without origin information, point-and-click has no way to know where to
go.  I am not sure what magic you imagine to be doing that job for
you...
