Excuse my non-technical, conceptual-only questions / thoughts / checking if I have this right in my head:


1)  There was no *permanent*  "double spend" right?   i.e. the transaction on the .8 fork would have eventually been orphaned / dumped / never credited to the address specified in the .8 block?

2)  The risk here (and reason why SwC shut off all deposits / withdraws for a few hrs until this was resolved) was that during this very odd period a sophisticated user could use multiple 0-conf services that would all at the same time believe they were getting the same coins, but after the blockchain becomes 1 again only 1 of the transactions would actually be included in the "real" blockchain?

Your points are my understanding.  The double spend was allowed only because the service provider here wasn't on the ball.
