strange thread behaviour in 1.9.8??

[plutek]

in "tips and tricks" : harmonic.ly ........

if the initial c'4 is removed, then the two notes within the <<>> behave
as polyphony rather than as a chord. this is consistent with the new
polyphony and chord syntax, but why does the initial c'4 force chord
behaviour?

if, after removing the initial c'4, i then place the multi-threaded chord
in a \context Voice {} block, then it DOES behave as a chord again.

perhaps, to have a consistent syntax, multithreaded chords should always
be placed in a Voice context now?
