KW41 Proximity Reporter

I have studied ch5.5 Proximity Reporter of BLE Demo Applications User's Guide.pdf.
This example is divided into two parts:
1. "Immediate Alert"
    Press High or Middle will immediately show different lights. There is no problem with this item
2. "Link Loss Alert Level"
    Press High or Middle, and try to reach a distance of 10m, there is no response at all.
   2a. I want to know what is the difference between High and Middle?
        What conditions will trigger High, what conditions will trigger Middle?

        What happens(phone alert sound  or  KW41 flashing red light) after it is triggered?
   2b. I found the following program, but did not understand his behavior?


Another question:
I saw the KW41's Proximity program and saw KW41 send battery to the phone.

But did not see RSSI transmitted value from KW41 to the phone(Proximity Reporter of IOT Toolblox).
Is RSSI calculated by the mobile phone itself, or is it transmitted to the mobile phone by KW41?
