If you are putting a molded edge on the wood there is usually wood below the molded edge area that the bearing rides on. When you reach the corner and start down the next edge the router bit will leave a radius of the molded profile the radius of the bearing on the bottom of the bit. The best way to find out is to rout a profile around the inside of a picture frame or hole in a piece of wood. You would insert the profile bit desired in the router collet and then set the depth of the profile. The bearing on the end of the bit will go against the inside edge of the frame below where the profile is being cut. Once the depth is set, place the router on the frame or edge of the hole, turn it on, and bring the router bit against the frame. Now move the router in a counter clockwise direction around the inside edge of the frame. When you reach the corner simply continue around it and down the next side. Now look at the corner that you just cut. You will see the radius that I'm talking about.
