Program execution during Flash operation?

Official Hardware Nano Family Nano Every

Practically this looks then in such a way if one flashed its program with a 1s delay starting from the 2.times that setup cannot be processed yet. At the beginning of the flash there is no D20 toggle on the left and only one toggle sequence on the right.
