Nop, those contact are the ICSP points to program that Flash Upgrade Board.
I used it once when an update failed and put my PICSTART unusable.
If one day it happen and you have a third party programmer who support the PIC on the flash upgrade module, send an e-mail to the Microchip TechSupport and they will send you the BOOTLOADER firmware. erase the PIC, then re-load the BOOTLOADER in. THEN replace the Module in the PICSTART and redo the firmware update.

Hello Steve,
You will notice on the PUM PCB there is a 5pin through-hole section on the PCB that you can use for reflashing the device. Pin 1 on the PCB should correlate to MCLR/VPP, Pin 2 VDD, Pin 3 VSS, Pin4 PGD, and Pin 5 PGC.
Maybe pin4 and 5 are reverted in that.. i had a problem when i flash it the first time and i revert those pins... My mistake or their.. i can't confirm since it worked BTW
I use PicStart for ICSP... no problem as now. See the folowing thread

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
