Both problems pointed out in this thread show a limitation in
the handling of volta brackets. A volta bracket is only printed
over contexts where the property voltaOnThisStaff is set to true.
At the beginning of a score, this property is automatically
set to true for the topmost Staff context and false in all other
contexts. This works well for normal scores, but not in the two
situations brought up here:
- When the topmost Staff is removed from some lines when you
use \RemoveEmptyStaffContext.
- When you add a new topmost Staff in the middle of a score using
staffAlignAboveContext.
In the second case, it's simple enough for the user to set
voltaOnThisStaff manually and it could be enough to add a note
to the documentation about this issue.
However, in the case of \RemoveEmptyStaffContext it's more tricky
to work around it manually, since the user does not know in advance
exactly at which bar a Staff will disappear. So, this situation should
really be handled automatically.

Why not start with all three staffs and remove the staff from the
first line?
Using:
\layout {
\context { \RemoveEmptyStaffContext }
}

Because that does not work either. The "1." volta is not displayed.
