right. your playbuf is two channels, and i believe the bus argument for out is 
a starting point for signals, so if you're sending a two channel sound it'll go to
bus #zero and then bus #one- and so on depending on the amount of channels.
from the helpfile:

Note that using the Bus class to create a multichannel bus simply reserves a series of adjacent bus indices. There is nothing to stop you from outputting a channelsArray larger than that range. You are responsible for making sure that the number of channels match and that there are no conflicts.

you're putting the sinewave on the first two busses,
and mulitplying it by an lfo.   this code appears 
to me that it should play on two channels.
if you did this:

lfo = SinOsc.kr(0.5,0,0.5,0.51);
output = Pan2.ar(SinOsc.ar(440),lfo);
Out.ar(0,output);

should do the same thing since Pan2 is a stereo (two channel) object,
and Out.ar's bus argument is set to and starts at zero.
