The point is that you can use this in a way like the patchmatrix of a VCS3.
You can sum several signals together, since you can flee the pin-shorting
problem 
into another dimension. The restriction is no more than one "pin" on one
row and column. (i.e. 8 pins per layer) If you'd like to place more than
one on one row or column, it must go to the next layer. 

One would have to use n*n SPST switches (e.g. 4066 plus resistors) to
emulate this behavior. (I don't see how 8 MUXes can do that.)

Bye,
 René
