Wrong. \change does not work to change a Staff from Staff to Staff, and
at the point of your first \change command, you do not yet have a Voice
(the temporary voices started in << \\ >> have just ended).
So the solution is to actually start a voice.

try \new Staff = "up" \new Voice {
and you'll actually _have_ a Voice that can change to the other Staff.
