sample from snippets library doesn't seem to work correctly?

[Chip]

In the LSR is "Demonstrating all headers" 
(http://lilypond.org/doc/v2.12/input/lsr/lilypond-snippets-big-page#Titles). 
The example code shows more headers than the example graphic. And when I 
copy/paste the sections from the code into jedit I am missing many of 
the headers. All of the headers for the second staff in the example, 
except two headers, are not shown in the .pdf. Is this correct and 
expected from the snippet? It'd be great if all the headers worked 
correctly for the second, and subsequent, \score blocks, same as for the 
first \score block.
