What's not clear in this video is this: The launch of B0006.1 in 2012 had TWO payloads, the primary (CRS-1) belonged to NASA - the secondary to (OG-2) belonged to Orbcom. The Falcon-9 did develop a premature engine shutdown about 90 seconds into the flight. SpaceX wanted to attempt a re-start of the bad engine (because Merlins are designed to be restarted like that) - but NASA vetoed that decision on the grounds that CRS-1 would make orbit without it (due to the Falcon-9's "engine out" capability).
Contractually, as the primary payload owner, NASA was allowed to do this. But in so doing, NASA doomed OG-2 to winding up in a bad orbit. Had SpaceX done what they wanted to do - the engine would very likely have re-started and the mission could still have been a 100% success.
OrbComm lost the satellite - but that loss was covered by insurance. Then (as Elon points out in the video) - because the PRIMARY mission was a success, by the standards of other launch companies - the mission as a whole is counted as a success.
But the point is, that had SpaceX been allowed to deal with their own rocket - it's quite likely that the mission would have been an unqualified success.
As it is, SpaceX proved that even with a shut-down rocket motor - Falcon-9 can still deliver it's primary payload into the correct orbit.
