XBee shield reset

Trying to understand the schematic for the XBee shield:


Pin 12 of the XBee (CTS) is connected to an NPN transistor (Q1) which pulls down a lead labeled RESET. I don't see that label anywhere else on the schematic--where does it go? Based on the PCB layer images at the link above, it looks like the collector of Q1 goes to the pushbutton and also pin 5 of the ICSP header. Is that right? I gather there's a typo on the schematic and the ICSP label on this lead is supposed to be RESET?

Another question is why does the XBee need to be able to reset the microcontroller chip through CTS?

Thanks, Joe
