Well keep in mind that these trailers were more of showcases really, but Oum has said he wanted to show off Adam which is why he was in the Black trailers doing his thing. As to his purpose in the trailer, well judging by the exchange between he and Blake, they were trying to destroy a shipment of Dust, for a reason I'm sure we'll find out later. :D
