Something else to highlight:
The match highlights were used as a sort of demo of the Xbox One's new video recording feature, which automatically records and stores locally the last five minutes of every game you play. Whenever something cool happens, you simply say "Xbox record" and it saves out the last 30 seconds of gameplay for upload and sharing.
This makes how the Games DVR function works a little more clear. So, basically the system automatically records the last five minutes of gameplay, and while you're playing if there is something you've done that you want to save, you just tell it to record it, and it'll grab the last 30 seconds.
I'm assuming, if you don't tell it to save anything, you lose anything that happened in the last five minutes as it begins a new five minutes. But also, you could probably go in 30 second increments saying "Xbox Record" and it'd save each clip.
