Two views, one camera
The bottom two views from the side launchers coming in to land were probably meant to show the camera shots from each individual booster, but they are actually just duplicates from the one camera on one of the boosters - this is clearly visible at the end as they come in to land on Landing Zones 1 & 2 and 'both' rockets land on the same LZ.
This takes nothing away from the achievement and the external shots clearly show the near simultaneous landing, but in the interest of completeness I thought I'd point it out before the conspiracy theorist/flat earth nutters get their teeth into it.
But, as you say, Awesome.
