glissando jumps between simultaneous expressions

In concurrent expressions (the "<< {} {} >>" syntax), a glissando in one
expression will terminate at the end of the next note in any expression,
rather than the next note in its own expression.  In the following example,
I'd like to see c'' gliss up to f'', but it instead glisses down to g.

\version "2.16.2"
{
  c'1 << {c''1 \glissando f''1} {g2 g g1} >>
}

Is this the intended behavior?  It seems wrong.
