RFC on Case 3 below. Thanks.

\version "2.20.0"
upper = f''1
lower = e'1
%% CASE 1: When the music in each simultaneous element begins with a
%% note, the upper staff is created first.
\score {
<<
\upper
\lower
>>
}
%% CASE 2: When there are sets preceding the notes in both branches,
%% the upper staff is still created first.
\score {
<<
{
\set Timing.vocalName = "2a"
\set Timing.vocalName = "2b"
\upper
}
{
\set Timing.vocalName = "2"
\lower
}
>>
}
%% CASE 3: When only the first branch begins with a set, the staves
%% switch places. Surprise!
%%
%% To fix this inconsistency, I suggest that as
%% Sequential_iterator::process() currently handles all the music up
%% to a given moment, Sequential_iterator::construct_children() should
%% handle all music at the initial moment--not just the first element.
