This is a consequence of Issue 2010, I believe, applied to version 2.19.16, 
which seems to do strange things when contexts terminate before others.  In 
developing the satb.ly built-in template I found I had to ensure all contexts 
which run out of notes prematurely had to be kept alive to avoid strange 
effects like this.

I suggest you consider using the built-in template for simple vocal pieces
(see 
http://www.lilypond.org/doc/v2.19/Documentation/learning/built_002din-templates)
 
which you may find easier to use anyway and which avoids this effect.  I've 
attached your source code converted to use it, as a teaser.
