The footage may be rough, but consider the environment and limitation of time and such. Playing at a convention isn't always the best environment to capture quality footage due to various limitations - like limited time with the game or just a sense of pressure to get high quality footage. I'm sure under normal circumstance a video of such play quality wouldn't be published, but in this instance they felt it was worth publishing as the game is nearing launch and this is new footage.
Again, just because you are in the game industry doesn't mean you are an expert gamer of a high skill level. Everyone has skills of varying degrees. I'm sure we'll see better footage come closer to launch once people have more time to play the game and get familiar with its play style, controls, and other mechanics.
Whenever I publish game footage, I try to devote time to the game before doing so. Sometimes that isn't an option when at media events and some outlets will ask the representative on site to play to ensure a quality gameplay video.
