Not necessarily, anon. YouTube Videos are usually made with a PC, we had this encounter on an XBox, which may make a difference.

Also, you might have noted that we stated their Sneak skill was low. If person who made the video's Dragonborn was sneaking, wearing muffled boots, etc. they may have not reacted due to that.

Finally, our test was done using a Khajiit, some NPC's don't seem to like Khajitts.
