I'm a little confused can anyone clarify my understanding of Auto-Switch on MPH.

Here is my understanding of the "Quick start guide".

"Algo switch mining (Port 17XXX)."
So this would switch only between coins of the *SAME* Algo such as; ETH, Musicoin, Expanse...and so on.

"Multi-algo switch mining (Port 12XXX)."
So this would switch between coins of *DIFFERENT* Algo's such as; Ethash, Cryptonight, NeoScrypt...and so on.

...but I have Claymore config as below, and I see it switching between the Ethash algo's only (ETC, ETH & Expanse) - just as I want it to; so what's the difference between using ports 12xxx & 17xxx if I'm only mining Ethash algo coins - or is there any ?
