Question on Qt animation framework

Hi all,
I have a technical question concerning animations.
All over the place in oxygen QPropertyAnimations trigger updates of widgets
with a slot/signal call a la:
connect(
animation, SIGNAL( valueChanged( const QVariant& ) ),
widget, SLOT( update( void ) ) );
Now, I also added:
connect(
animation, SIGNAL( finished( void ) ),
widget, SLOT( update( void ) ) );
The question is: does anyone know whether the second call necessary or
superfluous, or in otherr words, when an animation runs, is it certified that it
will always call a valueChanged signal with its endValue() before finishing.
I guess I can test it, but in case anyone knows that on top of his/her mind,
that would spare me some nasty QDebug
Thanks in advance,
Hugo
