The pilots initiated a go around from this event which is reasonable and proper, but for whatever reason the airplane settled back on the runway with the gear in transit to a retracted position. Not sure how, or why this would happened as when you push the TOGA switch on the 777, or just about any airplane for that matter, the power surge is significant and airplane just don't settle back on the runway.
Having worked with accident/incident investigations, I've seen multiple instances of a bounced landing where the ground spoilers effectively open after the aircraft is airborne again. This always brings the aircraft back to the runway with a large vertical acceleration (one incident had a 3.5G second bounce). It wouldn't surprise me if that was the case here, with the difference that the crew selected gear up after seeing a positive rate after the first bounce.
