Wow, though in theory I was aware of that principle, that would have
NEVER occurred to me! Thank you so much for that solution!

A minimal:

\new PianoStaff
  <<
\set PianoStaff.instrumentName = #"Primo"
{ \grace s4 r1 }
  >>

If I understand correctly:
It's simultaneous music, but the context-setting of instrumentName is
not synchronisized with { \grace s4 r1 }.
(It comes too late.)
Related to issue 34.

One should never set instrumentName in another place than \with to
avoid such things.
Usually the same holds for shortInstrumentName, but ofcourse
shortInstrumentName can be reset later. In this case you need to care
about synchronisation yourself. Although this may be a rare case.

Your example:

\score {
  <<
\new PianoStaff \with {
instrumentName = #"Primo"
shortInstrumentName = #"pr."
}
<<
  \new Staff = up \with {
\consists "Metronome_mark_engraver"
  }
  \relative c' {
\key a \minor \time 2/4 \clef treble
\ottava #2 \grace { e'''16[ fis gis] } 8 r r4 %1
\grace { e16[ fis gis] } 8 \ottava #0 r r4 %2
  }
  \new Staff = down {
\relative c' {
  \key a \minor \time 2/4 \clef treble
  \grace { s16 s s } 8 r r4 %1
  \grace { s16 s s } 8 r r8. dis,16 %2
}
  }
>>
\new PianoStaff \with {
instrumentName = #"Secondo"
shortInstrumentName = #"sec."
}
<<
  \new Staff = felice \with {
\consists "Metronome_mark_engraver"
  }
  \relative c' {
\key a \minor \time 2/4 \clef bass
\grace { s16 s s } 8 r r4 %1
\grace { s16 s s } 8 r r4 %2
  }
  \new Staff = hwaen {
\relative c' {
  \key a \minor \time 2/4 \clef bass
  \grace { s16 s s } r8 \ottava #-1  r4 %1
  \grace { s16 s s } r8  \ottava #0 r4 %2
}
  }
>>
  >>
}
