As seen in the fillet parameters.
Multiple means more then one
So you can have 3 - 4 or more different radius's from the same edge, this would be driven by the design intent of the product..
It looks to me like you need different edges not the same edge. If it were the same edge it would be a VARIABLE RADIUS. That's my take on it anyway. To me al it really does is allow you to put (3) different constant radi under one feature. I'll probably never use it, but you probably have to if you want to mess with the transition points as shown in the video.
