wdwerker is correct. If the top of workpiece tips away from the fence while the bottom is held against the fence it will pivot at the top of the rabbet. Everything above the pivot will move away from the bit but the banding below the pivot will move into the bit causing a shallow but certainly visible divot. If the depth of the rabbet happened to be exactly the same as the overhang of the banding the effect would be mitigated but that is not how the fence is designed. This problem is peculiar to the design of the fence and has nothing to do with the cutter. A fence of similar design mounted on a tablesaw would produce a similar divot if the top of the work pivots away from the fence. Using featherboards to keep the work against the fence works equally well for both router and tablesaw.

I would love a foolproof way of accurately setting the jointer knives on my Makita 2030 jointer /planer. For those who are unfamiliar with this machine, the jointer side has a fixed outfeed table so the knives must be set to the perfect height when installed in the cutter head. The problem is that the knives seem to move ever so slightly when the bolts are torqued down and the movement does not seem to be predictable.
