Actually, I think this has nothing to do with \instrumentSwitch itself, but 
only with the handling of instrumentCueName settings, which is messed up at 
the end of blocks like \note. In particular, in the following example, the cue 
name is printed in the second bar, too, although the cue name was not changed 
at all:

%%%%%
\version "2.13.37"
notes = \relative c' { c1 }
\score { 
    \new Staff = "one" { 
         \set Staff.instrumentCueName = "Cue"
         \notes
         d'1
    }
}
%%%%%

Cheers,
Reinhold
