IIRC default settings for  PianoStaff  is to remove either both staves
if both are "empty", either none if only one is empty (and the other one
contains notes).

If you want to remove the staves independently (if empty), try

\layout {
  \context {
    \Staff
    \RemoveEmptyStaves
  }
  \context {
    \PianoStaff
    \remove "Keep_alive_together_engraver"
  }
}


Cheers,
Xavier
