See also how to use alignAboveContext at

By the way, the 4th example of "Ossia staves" may be confusing. There's 
no need for any
\startStaff or \stopStaff in this particular example if it instead had 
been coded like
<<
 \new Staff = ossia \with {
   \remove "Time_signature_engraver"
   \override Clef #'transparent = ##t
   fontSize = #-3
   \override StaffSymbol #'staff-space = #(magstep -3)
   \override StaffSymbol #'thickness = #(magstep -3)
 } \relative c''{R1*3 c4 e8 d c2 }
 \new Staff \relative c' {
   c4 b c2
   e4 f e2
   g4 a g2 \break
   c4 b c2
   g4 a g2
   e4 d c2
 }
>>

\layout {
 \context {
   \RemoveEmptyStaffContext
   \override VerticalAxisGroup #'remove-first = ##t
 }
}

Explaining in detail why the current example in the manual works, is 
quite involved.

Well, we now have a bug report about the problem!
