No, it should not. There is
No, it should not. There is a "spreader" that goes in between the headrest tubes where it is inside the frame. The spreader pushes the tubes out against the frame. You should also have some rubber (looks like 1 inch pieces of tire tube) around the headreast tubes to increase friction against the frame.

Vendetta 2 and Silvio 2
Vendetta 2 and Silvio 2 headrests are the same see photos and description here.
I didn't capture a good photo of the scissor-jack clamp thingy that John invented in the link above but here is another photo of it. When you insert the headrest assembly into the frame tube you want the scissor-jack clamp to line up with one of the large round holes in the top of the frame. As you tighten the bolt down against the inside bottom of the frame tube, the hinged arms straighten and push the headrest tubes outward against the hydroformed frame (HF) tube to hold everything in place. The rubber sleeves further up and the foam plug should end up flush at the back HF tube opening.
You might want to shake your frame tube to see if the clamp is rattling around loose inside of it. If you can't find it, ask your bike shop to look for it. If you can't locate it ask John for help getting you a replacement.

I don't have either of the bikes that use this, but it sure is interesting to see how it works. Thanks, Eric, for the great photo and explanation. You have to admit, the design is ingenious!

Paul, you may also need to
Paul, you may also need to check that the scissor clamp is installed on your headrest the right way. Mine was on backwards, which means the bolt cannot be tightened after the headrest is inserted into the frame. If it's backwards then it's very easy to fix, just take it off and turn it around.

SCISSOR JACK FOR HEADREST
Excuse the double posting, I want people to find this note.
Some comments on the scissor jack. This applies to V2.0 that have already been shipped. The manual current shows the scissor jack installed through a hole on the HF tube. That is for the next production, done to try to make this less confusing.
Here is a picture of Vendetta, Silvio is the same, showing how the scissor jack fits:
Each wing is a U section, and with the open end facing up.
I had them put into a rubber sleeve to keep the unit together. Its possible some were shipped with the bolt entering the wrong side.
The screw pushes against the floor of the tube.
The barrel nut is a close fit. A smaller diameter barrel nut would mean the wings won't push out far enough.
I went with the scissor jack rather than internal clamps. Clamps are easier to understand perhaps, but not as neat. I want the headrest to project smoothly out of the frame. Hard to make the headrest legs any closer together.
