I'm going to disagree with Terry & Barry and tell you yes it should. If you'll look at your fence closely you will see an area just past the cutterhead on the outfeed side of your fence that is wider than the rest of the fence and rounded to limit scoring the tabletop.
I recently rebuilt a dj 20 and struggled with setting the collar to hold the pin at 90 degrees. I realized the set screws in the collar had made indentions in the rod and kept falling back into the same position when tightening. You have a rod that floats inside 2 bushings and 2 collars. One collar has the indents for 90 and 45 degrees that your locking pin goes into and the other collar is for the friction locking mechanism. Loosen set screws in both collars so you can rotate the rod to a fresh spot for your set screws to bite into. Retighten the collar the friction mechanism locks down on but leave the collar with the indents for the pin loose. Set your fence to 90 degrees and lock down tightly. Recheck for drifting when tightening and compensate if needed. Once you are satisfied your fence is at 90 degrees then tighten the set screw in the collar making sure your pin is securely set in the indention.
