It can hardly be an accident when as ABCbits wrote you either have to copy and paste the Genesis address from somewhere, or remember it exactly and typeit character by character, all 52 of them.
That's hardly an accident to me.
The source used in the article (Arkham Intelligence) apparently doesn't take into account any of this, and wrongly assumes that the transfer was made by accident, when it clearly is not possible for it to be that way.
