Bonjour, Eddie,
That's actually the whole idea. You'll want to do a plunge cut to cut the rubber edge. This makes it zero-clearance for your saw. The result is a guiderail you can position exactly to the edge of the cut and has fiber support for the fibers at the front of the saw.
You'll also want to put the green splinter guard on the saw (front right side) and plunge through that as well. That's what gives you off-cut fiber support on the front of the saw.
All this should be spelled out in the user's manual, but no matter, you're on the right track (-chuckle-) so long as you haven't tried moving the blade in the meantime [crying]
