[ODE] Degree of liberty of Slider joint

I was looking at Slider Joint on the wiki page :

and was thinking "Hey this joint can rotate around the sliding axis".

Then I looked at code in joint.cpp and there is 5 constraints or 6 if 
fmax exists so the rotation around the sliding axis is not possible.

So my questions are:

Is this true ?

If this is true maybe the figure in the wiki should have a rectangular 
shaft to explicitly state that there is no rotation around the sliding 
axis ?

Do you know if someone implemented a Slider which has no constraint on 
rotation ?
