I saw that video the other day, still very misleading by a factor of about 4 (in area). In that first shot, his forearm is pointing up, so his hand isn't near arms length, but the screen hand ratio looks about right for if it were at arms length. So depending on what his upper arm is doing, the FOV is about doubled (approx 60 degrees wide hoorizontal instead of ~30 degrees), giving it about 4 times too much area in the shot.

To me it just reminds me of Kinect and Molyneux's Milo demo. The Minecraft demo on the table they gave for example was very misleading, because when the camera guy got close to the table, he could still get the whole thing in the shot. Standing by the table you would only actually be able to see tiny slices at a time.

Some outlets have called it out as a big issue--The Verge ( http://www.theverge.com/2015/5/1/8527645/microsoft-hololens-... ), and Tested are two I've seen. I still think it is cool and it is the best that has been broadly publically demoed (Magic Leap has only been shown to a select few, and not in any kind of portable form; and at least some of their embodiments in their patents show only around 30 degree diagonal), but all the footage is misleading about FOV and most of it completely fakes occlusion. Google was guilty of the same with at least one of their big videos around a day in the life of Google Glass.
