@NickGammon Reset Circuit

Hi Guys,
Reference to Nick Gammon Github projects GitHub - nickgammon/arduino_sketches: Publicly-released sketches for the Arduino microprocessor

I'm building a board in order to set the fuses of some ATmega328p that I believe I have set in a wrong way and now the chips seem to be died.
My mistake.
I think I can use your project in order to resume the chips. The project does exactly that for what I have understood. That's great.
Looking at the reset circuit I have a concern and I would like to share with you all what is my concern.
There is an output ('VCC' on D5) from the Arduino Uno that goes to the reset circuit on the target board. In the firmware this wire is configured as an output and at initialization time it is set to 'low' (line 271..278 of HV_Parallel_Utils.ino).
Later on, VCC is set to high at line 248, same file.
But if this output is set to low, there is a sort of short circuit between the 'VCC on Target' and GND.
The short circuit current can be greater than the maximum that the Arduino Uno's output can accept?
Am I making a mistake? May be.
What do you think about?
Thanks for reading.
Best regards,

D5 is providing the VCC for the target.

Thanks 'srnet'.
So the Arduino Uno is the power supply for the target board via the 'D5' pin
and at the same time, upon powerup, a pulse is generated on the reset pin of the target.
This seems to me logical and correct.
Best Regards,
