Do you mean that the staff is not removed in the first system? That's 
just the difference between \RemoveEmptyStaves und \RemoveAllEmptyStaves.

The keepAliveInterfaces list defines which types of "event" prevent a 
staff from being removed. So:

%%%%
\version "2.20.0"
\language "english"

\layout {
  \context {
    \Staff
    \RemoveAllEmptyStaves
  }
}

killMeAtAllCosts = \set Staff.keepAliveInterfaces = #'()
resurrectMe = \undo \killMeAtAllCosts

fillBar = \relative c' { g'8[ g g g g g] | }
fillLine = { \fillBar \fillBar \fillBar \fillBar }

partA = {
  \key d \major \time 6/8 \clef "G"
  \fillLine \break
  \killMeAtAllCosts \fillLine \break \resurrectMe
  \fillLine
}

partB = {
  \key d \major \time 6/8 \clef "G"
  \fillLine
  \fillLine
  \fillLine
}

\score {
  <<
    \new Staff \with { shortInstrumentName = "Pt A" } \partA
    \new Staff \with { shortInstrumentName = "Pt B" } \partB
  >>
}

%%%%
