In this case, the user sent low fee transaction first, found out it does not propagate well, almost all his peers reject it. He then sent same coins again, with higher fee.
So the first tx that was confirmed was the first sent which is labeled the double? This 1 is confusing thx for the explanation.
Yes. It only appears it came after, because no one saw it, until it was in a block (the time of that transaction is the same as of the block it was minted into).
