Reverse Loop inside another reverse loop

Ed
 

I have a reverse loop that is controlled by a PSX-AR and I have added a quarry at the end of this loop that is controlled by a wye.  I understand that this creates another reverse loop but that I can manually control the turnout at the end of the wye using a DPDT switch. My question is: what does this do to the PSX-AR sensing functions - with or without another loco in the original loop?
