A Question About "Analog Input Example Code"

[ProtoNoob]

So, I am making a new kind of instrument and your MUX and accompanying code is just what I am looking for. My question about the code is more of a theoretical one that a practical one. In your code, you loop through the First MUX taking just the analogRead[0]. You then loop through the Second MUX taking just the analogRead[1]…and so on. Is there a particular reason that you did it that way rather that the code below.

for (int i=0; i<16; i++)
  {
    digitalWrite(CONTROL0, (i&15)>>3); 
    digitalWrite(CONTROL1, (i&7)>>2);  
    digitalWrite(CONTROL2, (i&3)>>1);  
    digitalWrite(CONTROL3, (i&1));     
    mux0array[i] = analogRead(0);
    mux1array[i] = analogRead(1);
    mux2array[i] = analogRead(2);
  }

Would the code I provided not be more performant? Perhaps your code helps prevent analog cross talk? Or is more performant for some reason I do not understand? Honest question here.
