I think something else is happening.  I don't believe in 
nondeterministic
lilypond code.  :)

What's the *2/3 for?  Are they really triplets?

If so, how about this?

\score {
 \context PianoStaff <<
  \context Staff = "up" {
     \key f \major
\voiceTwo
     \change Staff = "down"
     f,4 \change Staff = "up" f' f''2
\oneVoice
     f'4 f' f' f' f' f' f' f' f' f' f' f'
  }
  \context Staff = "down" {
     \clef bass
     \key f \major
\voiceOne
     \times 2/3 { s8 a c' }

     \change Staff = "up"
     \times 2/3 { s8 a' c''}
        s2
\oneVoice
     \change Staff = "down"
     f4 f f f f f f f f f f f
  }

}


If you don't like the triplet beams, then you could go back to the *2/3 
thing.

If they're real 8th notes, then you'd want this:
\score {
 \context PianoStaff <<
  \context Staff = "up" {
     \key f \major
\voiceTwo
     \change Staff = "down"
     f,4 \change Staff = "up" f' f''2
\oneVoice
     f'4 f' f' f' f' f' f' f' f' f' f' f'
  }
  \context Staff = "down" {
     \clef bass
     \key f \major
\voiceOne
     a8[ c']

     \change Staff = "up"
     a'8[ c'']
        s2
\oneVoice
     \change Staff = "down"
     f4 f f f f f f f f f f f
  }
>>
}


In any case, you really shouldn't be playing games with s32.  Unless 
you know that what
you're doing is very complicated, or you're trying to work around a 
known bug, look for
other solutions to your problem.  In this case, I think that voices 
(see the section on
Polyphony for more details) is the way to go.
