Just a pragmatic choice.  MIDI can specify only one instrument per
track; and a staff is translated to a MIDI track.

If you want different instruments for two voicess, you must put them
on different staffs, ie, you probably need a dedicated midi score
definition:

   \score {
     \context Staff < \instrI \instrII >
     \paper { }
   }

   \score {
      <
        \context Staff=I \instrI
        \context Staff=II \instrII
      >
      \midi { }
   }
